BACKGROUND

Energy storage devices or systems are capable of storing energy in various forms (e.g., mechanical, chemical, electrochemical, potential, electrical) for later release and use for individual, multiple and/or simultaneous applications. Their operation can be controlled and managed.

SUMMARY

The present disclosure provides a software operating system to operate, optimize and network energy storage systems for multiple value streams. Energy operating systems of the present disclosure can coordinate the components of an energy storage system to capture value from any number of services that the energy storage system can provide individually and/or as a networked configuration. The energy operating system can operate locally as an embedded system on the energy storage system and/or on external servers.
In some situations, the core of the energy operating system is an energy computing module to optimize the operation of the energy storage system based on adaptive rules and algorithms for each of the services. The inputs to the rules and algorithms are exterior pricing signals, communications signals, rate structures, electrical system status, electrical system forecast and operator preferences. The outputs are adaptive operational signals for energy storage system hardware components and/or peripheral devices, energy and economic data, including control signals for other devices and reporting functions.
The software can be designed or implemented as an operating system. The operating system can be modular. The appropriate energy services for the site and desired functions can be installed, updated and maintained as a computer program or application. Further, the library structure of the energy operating system can allow any energy storage system hardware component and/or peripheral electrical devices to be integrated with drivers, thereby not requiring changes in the energy services. Additionally, the library structure can include operational libraries based upon evolving standards, which can be designed or otherwise configured to be updated without affecting other modules of the energy operating system. Finally, the database architecture of the energy operating system can have a private side for system operations and a public side for the storage, acquisition, publishing and broadcasting of energy availability data, energy operation data, economic data and operational signals.
An aspect of the present disclosure provides a system for automating, managing and/or monitoring an energy storage system. The system comprises a plurality of drivers, a set of libraries, and a plurality of applications. Each driver among the plurality of drivers can be programmed to enable communication with an energy storage system upon execution by a computer processor. Each library among the set of libraries, upon execution by a computer processor, can implement energy-related data transformations and/or energy-related data calculations using input from the energy storage system, wherein the input is provided with the aid of a given driver among the plurality of drivers that is selected for the energy storage system. Each application among the plurality of applications can be selectable by an operator of the system to perform an energy- and/or economic-related function using input from the energy storage system that is provided with the aid of the given drivers and libraries.
In another aspect of the present invention, a method of creating models for use in a predictive analytics engine and subsequent operation of the engine in an adaptive energy operating system is described. The performance of an energy application for an energy asset is modeled. The energy asset health for an energy asset is modeled. The cost efficiency for the energy asset is modeled. A forward operating profile for the energy application is created. A forward availability profile for the energy asset is created.
In another aspect, a method of operating an adaptive energy operating system in communication with one or more energy assets is described. A forward availability profile for an asset and a forward operating profile for an application are received. A predictive analytics data package containing three models is received.

A distributed energy asset in the plurality of distributed energy assets can be configured to perform a plurality of energy applications. The platform can be configured to generate an application performance model for each of the plurality of energy applications performed by the energy asset, generate a health model for the energy asset, and generate a revenue generation model for the energy asset. The platform can then generate an energy asset model for the energy asset based on the application performance model, the health model, and the revenue generation model. Based on the energy asset model, the platform can create an initial forward availability profile for the energy asset. The initial forward availability profile can define at least a distribution of battery capacity among the plurality of energy applications performed by the energy asset that co-optimizes performance of the plurality of energy applications.
In some embodiments, generating the application performance model for each of the plurality of energy applications can involve analyzing historical output data captured during performance of each energy application by the energy asset.
In some embodiments, generating the health model for the energy asset can involve analyzing degradation of the energy asset over time.
In some embodiments, the platform can be further configured to dynamically optimize operation of the energy asset in real-time and during operation by updating the energy asset model based on a difference between one or more predictions derived from the energy asset model and actual operational performance of the energy asset. Upon updating the energy asset model, the platform can re-compute the initial forward availability profile.
In some embodiments, the platform can be further configured to create a forward operating profile for each of the plurality of energy applications performed by the energy asset. In some embodiment, the platform can be further configured to combine the forward availability profile and the forward operating profile with energy asset characteristic data and historical data, thereby enabling predictive analysis. In some embodiments, the platform can be further configured to create a predictive analytics data package containing the forward operating profile and the forward availability profile. In some embodiments, the platform can be further configured to perform predictive analytics for operation and management of the distributed energy asset. In some embodiments, the platform can be further configured to simulate performance of the plurality of energy applications when performing the modeling.
In some embodiments, generating the health model for the energy asset can involve examining degradation as a function of use. In some embodiments, generating the health model for the energy asset can involve examining degradation as a function of calendar life.
In some embodiments, generating the revenue generation model for the energy asset can involve dynamically connecting energy operations with financial data. In some embodiments, generating the revenue generation model for the energy asset can involve predicting revenue that the energy asset is expected generate over its lifetime.

DETAILED DESCRIPTION

While various embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed.
An aspect of the disclosure provides a system comprising an adaptive energy storage operating system (also “adaptive operating system” or “energy operating system” herein). The system can include an adaptive energy storage operating system that is programmed or otherwise configured to communicate with an energy storage system, and its components (e.g., power conversion system, battery management system, electrical meters, electrical relays, etc.) and optimize the operation of the energy storage system, such as, for example, based on adaptive rules and algorithms.
The system can comprise one or more device drivers, each configured to operate or control a given energy storage device. A given driver can be a program that can run on the system to operate or control an energy storage device or energy storage system component. The driver can communicate with the energy storage device through a computer bus of the system or communications subsystem that is connected to the energy storage device. The driver can enable sophisticated communication of data (e.g., automation, algorithmic control) between the device and the system. In some cases, the driver may interface with or one or more industrial control systems, such as, for example, one or more device-specific drivers. The driver may utilize one or more communication or control protocols. The driver can communicate with various types of devices (e.g., devices requiring different communication or control protocols) such that devices can interface with the system in a plug and play fashion. The drivers of the present disclosure can enable the system to interface to numerous types of drivers and devices. In some embodiments, the drivers of the present disclosure can be selected by a user, automatically detected upon connection of a device, or a combination thereof. The drivers can enable one or more devices to be integrated with the adaptive operating system without affecting the remainder of the adaptive operating system.
In some examples, a system comprises an adaptive energy storage operating system. A user couples the system to an energy storage system, and the adaptive energy storage operating system automatically recognizes the type of energy storage system and configures the system for use with the energy storage system. As an alternative, an operator can configure the system for use with the energy storage system by selecting appropriate drivers.
In some examples, when a calling program (e.g., an energy management program or an energy service application) of the system invokes a routine in the energy operating system core and/or in a driver of the system, the driver issues one or more commands to the energy storage device. Once the energy storage device sends data back to the driver, the driver can invoke routines in the original calling program.
A driver can be hardware-dependent and operating-system-specific. The driver can provide interrupt handling required for any necessary asynchronous time-dependent hardware interface. The driver can enable the system to interface with a power conversion system and/or a battery management system of an energy storage system.
The system can further include one or more libraries. A library can be a collection of implementations of behavior, written in terms of a language that can have a well-defined interface by which the behavior is invoked. The library can be used by any one of a plurality of programs of the system. A given library can include reference materials for the system.
The system can include a plurality of libraries. In some examples, the system includes a utility rate structure library, a smart grid communication protocol library and a manufacturer operating parameters library. A given library can perform or be used to perform actions, transformations and calculations with various operating energy storage device operating parameters. In some cases, an application can be configured to perform such actions, transformations and calculations.
The system can include applications that are programmed or otherwise configured to run on the adaptive operating system. An application can be selected by an operator of an energy storage device for various uses. An application can be provided for various functions (e.g., actions, transformations, calculations) or energy services, such as, for example, detecting energy storage device charge, ancillary services, optimum demand charge management, time of use shifting, demand shifting, demand response, electric vehicle charging.
Libraries and/or applications can perform actions, provide limitations on system parameters, transform and calculate data and operation signals, and generate commands for drivers to deliver to energy storage system devices and components. In some cases, the core of the energy operating system can perform the calculations. The drivers can translate and relay communications and control signals.
FIG. 1 shows a system 100 comprising an energy operating system 101, in accordance with various embodiments of the present disclosure. The energy operating system 101 includes one or more energy service applications 102, 103, 104 each corresponding to one or more functions or energy services. Examples of functions of energy storage services include, without limitation, demand charge management, time of use shifting, demand response, ancillary services, energy capacity, electric vehicle charging, spinning reserve capacity, ramp rate service, renewable energy firming, frequency regulation, voltage regulation, transformer unloading and management, peaking power, emergency and backup power services, and power quality services. The energy operating system 101 can comprise software for implementing the applications 102, 103, 104. The energy operating system can be implemented on a computer system (e.g., system 200 in FIG. 2). The system can be implemented locally (e.g., at a site of an energy storage device). Software can run different applications locally. In some cases, the system can communicate with one or more other systems over a network. In some cases, the energy operating system can be implemented locally and centrally (e.g., at a central site controlling multiple energy storage devices).
In some embodiments, the system 100 can include various frameworks 105 for building the applications 102, 103, 104. The frameworks 105 can be separate from the energy operating system 101. As an alternative, the frameworks 105 can be included in the energy operating system 101. For example, the energy operating system 101 can include a security framework 106, which can comprise security protocols and data protection hardware and software, such as, for example, firewall, active event alerts and authentication software. The energy operating system 101 can include a user interface (UI) framework 107, including, for example, software and graphical tools for implementing a graphical user interface and a communications interface for interfacing with one or more devices, networks, or other systems. The system can further include various tools 108, including, but not limited to, tools for building drivers, tools for setting permissions (e.g., user access level, clearance, permission to override automatic control, permission to export or report data), tools for creating user accounts etc.
The energy operating system 101 can further include one or more libraries 109. The libraries can include reference data or reference materials, such as, for example, utility rate structures. The reference data can be for local economic values and operational parameters to be utilized in applications, algorithms, and programs. The utility rate structures can include local economic rate information for supply and demand on a power basis and on a total energy basis. In some cases, the libraries comprising different reference materials can be provided separately. In other cases, one or more libraries can be combined and/or integrated.
Further information which may be stored in libraries can include statistical data, exterior pricing signals, communications signals, rate structures, electrical system status and operator preferences. In some embodiments, such data can be included in one or more databases 110. The databases 110 can be local (e.g., on site and accessible over a network), global (e.g., centrally maintained and locally accessible over a network), or a combination thereof (e.g., a copy of a database can be maintained locally in addition to a global database). Further, the databases 110 can have a public portion (e.g., available to one or more users over a network or published or reported externally) and a private portion (e.g., available for system operation, to one or more users of the energy operating system, or monitoring data saved for troubleshooting purposes). The data in the databases 110 can include, for example, device-level data, usage and performance data and energy and economic data.
In an example, the libraries 109 can further include one or more drivers. The drivers can enable different devices to be plugged in and integrated with the system locally without affecting other parts of the system (e.g., without affecting applications implemented by the system). The drivers enable hardware (e.g., energy storage devices) to be integrated with the energy operating system in an abstract fashion.
The frameworks 105 can further include an energy networking framework 111 and an energy computing framework 112. The energy networking framework 111 can include, for example, software, tools, methods and/or protocols for communication between energy operating systems; for arranging, conditionally aggregating operations, coordinating and managing energy operating systems and energy storage devices over a network; for calculating, analyzing and balancing energy streams among the energy devices; and for storing or delivering energy from the energy storage devices (e.g., in coordination with a grid operator). The energy computing framework 112 can include, for example, software, tools, methods and/or protocols for measuring, calculating, transforming and monitoring operations, performance, generation, storage, delivery and distribution of energy in one or more energy storage devices. The frameworks 111, 112 (or any of the frameworks 105) can include algorithms and logic that may alternatively be included in one or more of the applications of the energy operating system 101. The frameworks 111 and 112, or any of the frameworks 105, can include commands, algorithms and logic for interfacing or calling another framework. For example, the energy computing framework 112 can include the capability to interface with, request information from and submit commands to one or more drivers. Thus, when one of the applications of the energy operating system is implemented, it can employ one or more frameworks, and each framework can provide functionality needed for implementing the application. Various levels of functionality may be distributed across applications and frameworks to streamline execution across various applications of the energy operating system. For example, functionality may be modularly arranged or organized to streamline co-optimization across applications, as described in more detail elsewhere herein.
The energy operating system 101 can be a modular software system. For example, the applications 102, 103, 104 and libraries and drivers 109 can be added on to the system module by module (e.g., device by device, application program by application program). In some cases, other frameworks 106, 107, 108, 110, 111, 112, 113 can be modular. The core 101 of the system 100 can include an energy computing module for optimizing the operation of the energy storage system based on adaptive rules and algorithms for each of the services (e.g., services implemented by applications 102, 103, 104). The co-optimization across applications can be implemented in accordance with one or more objectives of the energy operating system, such as, for example, an objective based on economic considerations (e.g., maximization of profit, maximization of capacity factor), or an objective based on reliability considerations. Thus, the energy operating system can be used to coordinate the components of an energy storage system (or multiple networked energy storage systems) to capture value from the energy services provided using the energy operating system (e.g., energy service implemented with the energy service applications).
The implementation of the applications can lead to various outputs, such as, for example, adaptive operational signals (e.g., control signals) for energy storage system hardware components and/or peripheral devices (e.g., communicated to devices using the drivers of the system).
The outputs can include reporting functions. The reporting functions can be implemented as one or more applications in conjunction with one or more frameworks 105, such as, for example, the library 109, the database 110, an energy accounting framework 113, and or other modules. The energy accounting framework 113 can include an economic interface, including generating standardized economic reports, calculating economic parameters and indicators, performing statistical analysis, performing economic projections and forecasts etc. In some examples, the reporting functions can be generated automatically within a database (e.g., programmed database) or implemented within a library. The present disclosure provides hardware for implementing operating systems provided herein. The hardware can be dedicated for use with energy storage systems or shared for the operation of other energy system components and functions.
FIG. 2 shows a system 200 comprising a computer system (or server) 201 with an adaptive energy storage operating system, in accordance with various embodiments of the present disclosure. The server 201 includes a central processing unit (CPU, also “processor” and “computer processor” herein) 205, which can be a single core or multi core processor, or a plurality of processors for parallel processing. The server 201 also includes memory 210 (e.g., random-access memory, read-only memory, flash memory), electronic storage unit 215 (e.g., hard disk), communication interface 220 (e.g., network adapter) for communicating with one or more other systems, and peripheral devices 225, such as cache, other memory, data storage and/or electronic display adapters. The memory 210, storage unit 215, interface 220 and peripheral devices 225 are in communication with the CPU 205 through a communication bus (solid lines), such as a motherboard. The storage unit 215 can be a data storage unit (or data repository) for storing data. The server 201 can be operatively coupled to a computer network (“network”) 230 with the aid of the communication interface 220. The network 230 can be the Internet, an internet and/or extranet, or an intranet and/or extranet that is in communication with the Internet. The network 230 in some cases is a telecommunication and/or data network. The network 230 can include one or more computer servers, which can enable distributed computing, such as cloud computing. The network 230, in some cases with the aid of the server 201, can implement a peer-to-peer network, which may enable devices coupled to the server 201 to behave as a client or a server.
The server 201 can include an operating system with a program that is configured to interface with a load, such as an energy storage device or power grid, a power meter or a power converter. The server 201 is configured to communicate with various types of energy storage devices and/or power generation systems, such as batteries, hydroelectric devices, wind turbines, photovoltaic systems, geothermal systems, nuclear power plants, and the power grid. The server 201 includes drivers for communicating with various types of energy storage devices, power meters and/or power converters, libraries for performing various functions, and applications for permitting a user to perform various user-specific functions in the context of energy storage. The server 201 in some cases is exclusively dedicated to energy storage. In some cases, the operating system of the server 201 includes no more than the features (e.g., drivers, libraries) that are required to permit the server 201 to be used to manage, operate, monitor and/or optimize energy storage devices and power generation systems.
The server 201 is in communication with an energy storage or power generation system 235, such as a battery (e.g., solid state battery, electrochemical battery), power grid, renewable energy source (e.g., wind turbine, photovoltaic system, geothermal system, wave energy system). The server 201 can be in communication with other load 240, such as a power grid (e.g., smart grid) or local loads (e.g., lighting systems, heating/cooling systems, and computing systems). The server 201 can be in communication with a power meter, power relay, or a power converter. The energy storage or power generation system 235 can be coupled to the load 240 for distribution/transmission of energy between the energy storage or power generation system 235 and the load 240.

Adaptive Automation Control

Present energy automation control software (eACS) and energy operating systems are able to perform the basic function of managing the operation of one or more energy assets or devices. However, they lack tools and features that are critical for the ultimate goals of energy efficiency and economic optimization. One type of conventional eACS is SCADA, known to people skilled in the field of energy operating systems. These systems facilitate control of energy assets/devices but do not have native energy applications; they are essentially communication channels that operate among energy applications, energy devices/assets, and data stores. Although there are financial tools, such as spreadsheets and other modeling software in the market, they do not link directly to SCADA or similar existing energy systems and lack any degree of integration into these conventional systems.
Another disadvantage of SCADA and similar systems is the need for manual intervention and decision-making by human operators who oversee the operations. It is difficult for such operators to co-optimize applications and devices and are more likely to make errors and not see potential inefficiencies regarding various aspects of the system.
Recognized herein is the need in the energy operating system and automation control field for more sophisticated tools and features that enable predictive analytics, dynamic and intelligent aggregation, asset-availability balancing for operations, the co-optimizations of multiple operations, and forward-lifetime modeling of energy storage systems and other energy assets. Energy automation control software and operating systems need to advance to the next level and enable energy asset optimization and cost savings. In other words, energy control and operating systems should have more intelligence by integrating tools such as predictive analytics engines, rich data streams and methodologies needed to operate energy systems.
The present disclosure provides methods and systems for optimizing an energy storage system's lifetime performance and application economics. These examples and embodiments are provided solely to add context and aid in the understanding of the invention. Thus, it will be apparent to one skilled in the art that the present invention may be practiced without some or all of the specific details described herein. In other instances, well-known concepts have not been described in detail in order to avoid unnecessarily obscuring the present invention. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the invention, these examples, illustrations, and contexts are not limiting, and other embodiments may be used and changes may be made without departing from the spirit and scope of the invention.
Methods and system for linking a transactive energy system design to process automation are described. One aspect of the invention includes a design process that provides a predictive analytics engine at its core. At a high level, this design process includes three models: application modeling, health/asset modeling, and revenue modeling. The health/asset model has many inputs, for example an energy storage system health model is the combination of the application model with storage life characteristic data, described below, that comprises electrical efficiency, effective capacity, and capacity fade as a function of temperature, Voltage range, and calendar life. The health/asset model can be for any type of device/asset. These models enable a predictive analytics engine to inform energy automation control software (eACS) how to operate. The inventive concept involves utilization of various core data communication methods. One primary aspect is that the predictive analysis uses the same algorithms and processes as those used in the actual eACS and energy operating system. The continuity from analytics to operations improves the accuracy of the economic models, which reduces risk to financial planning and system financing.
At the center of the present invention is the energy operating system which includes eACS. The energy operating system described here is developed by Growing Energy Labs, Inc. (GELI) of San Francisco. As described in pending U.S. patent application Ser. No. 13/898,283, the eACS developed by and assigned to GELI has numerous novel features and is referred to as an adaptive energy operating system (aEOS). For example it is able to operate one to multiple applications from one or more assets, providing a flexibility and scalability not found in conventional ACS. It also has other features although not directly related to the inventive concepts described herein. A primary methodology described in the earlier patent and important to the novel features described here is that every energy asset or device can be utilized for multiple applications. The inventive concepts of the present invention are embodied in the aEOS but parts may perform functions and create data streams from other locations. It is helpful to keep in mind that the benefits and utilization of the present invention are not dependent on novel improvements in the aEOS described and claimed in pending U.S. patent application Ser. No. 13/898,283. The methodologies and data streams, and benefits derived therefrom of the present invention, can be manifested or realized in a setting where there is only one energy asset (e.g., an energy storage system) and one application. However, it is expected that the methodologies and data streams of the present invention will be used in more complex environments having multiple assets, applications, consumers, etc., and that the flexible, scalable, multiple-application enabled aEOS described earlier will likely be utilized.
In one embodiment of the present invention, there are two enabling core data methods, characterized as data streams. These data streams, combined with certain storage lifetime characteristics data, described below, and historical data drive the transactive energy aspect of the present invention which includes predictive analysis, dynamic and intelligent data aggregation, asset-availability balancing for operations, multiple operations co-optimizations, and forward-lifetime modeling of energy storage systems and other energy assets.
FIG. 3 is a block diagram showing an aEOS configuration in accordance with one embodiment of the present invention. An aEOS 302 includes a predictive analytics engine 306. It also has one or more energy-related applications 308. Operating in conjunction with or within aEOS 302 is a server for creating and utilizing certain profiles, specifically a forward operating profile (FOP) and a forward availability profile (FAP), referred to as a FOP/FAP server 310. Adoptive energy operating system 302 is in communication with one or more energy assets or devices 312. There is a wide variety of such devices or assets, a few common examples include energy storage systems (ESS, battery plus power converter), HVAC, load switches, lighting, chillers, EV chargers, solar panels, CHP, and diesel generators. In the described embodiment, an ESS is used to illustrate the present invention. Applications 308 in aEOS 302 direct the function performed by the ACS on the energy devices—it is the type of management or service being done on the devices. These applications include demand response, demand management, time-of-use shifting, frequency regulation, power quality, backup power and load islanding, etc. Also contained in aEOS 302 are energy asset drivers 320 for communicating with assets 312.
One of the outputs from aEOS 302 is an asset operating profile 314, described below. Another output is FAP of an asset 318. One of the inputs to aEOS 302, specifically for predictive analytics engine 306, is a predictive analytics package 316.
In one embodiment of the present invention, aEOS 302 contains intelligence on how to co-optimize performance of the one or more devices that are in communication with it. In an alternative embodiment, there is also a cloud configuration wherein the aEOS 302 operates on remote servers and connects to devices/assets via a gateway component. The aEOS 302 is able to perform certain predictive analytics with respect to the operation and management of the devices. This is done by the predictive engine in aEOS 302 which operates on what is described below as a predictive analytics package.
The predictive analysis of the present invention uses or simulates energy service applications, algorithms, and methods that are very similar or identical to those used in aEOS 302. This aspect of the invention, combined with using rich historical data from the customer, enables highly accurate predictions with respect to ESS performance and other asset optimization and cost efficiency (financing).
One critical component of the present invention is a predictive analytics package created from specific types of modeling. Outputs of this modeling (or design process) are profiles that are ultimately used to optimize asset operations. These are shown in FIG. 4. In one embodiment, three types of modeling are performed. One may be described as application (or performance) modeling. The objective with this modeling is to examine how an energy asset is performing over time by looking at historical output data for the device while operating to perform an operation/application. Another type is health/asset modeling of the energy device. With this modeling, an asset, such as an ESS or HVAC, is examined to see how it degrades as a function of being used. There is also a financial model for the asset or system. Here revenue that the asset is likely to generate over its lifetime by performance of a specific application is predicted. In one embodiment a dynamic rate structure library is used to connect energy operations to the economics in real time. Such economic modeling or logic does not presently exist in conventional ACS (typically an external business intelligence software suite is used to derive similar type data and decisions based on such software are made by human operators).
In one embodiment, historical data may be used to perform the modeling. This data is obtained from the entity operating the ACS and energy assets. For example, historical data on the different applications and devices may be derived from smart meters, bills, and other data.
In a specific embodiment of the present invention in which an ESS is described, storage life characteristics data (SLCD) is used in the modeling and overall predictive analysis of the asset for a specific application. In one implementation, this data is a multidimensional data set that enumerates how the battery performs for efficiency, effective capacity, and capacity fade as a function of charge rate, discharge rate, voltage range, temperature, and calendar life (battery age). The SLCD is used mostly in asset/health modeling but may be used in the other models. The SLCD is used as matrix element data, database architectures, or fit with parametric functions.
In one embodiment, the data is used to model battery degradation, application performance and economic returns. Historical data from the customer is combined with a specific application, for example, demand charge management (DCM), to generate a forward operating profile (FOP) for the energy storage system. A FOP may be instantiated, for example, as the output from a power converter system to the energy storage system. For an energy storage system, the battery's state of charge and the power converter's power capability may be considered as the asset's forward availability profile (FAP). A battery's energy storage capacity may be assigned, in full or in part, to one or more applications. For example, when the probability of peak demand event is high, all the battery's capacity may be assigned to the DCM application, and the battery will be unavailable to perform other applications (zero FAP). When the probability of a facility peak is low, only a portion of battery's capacity will be assigned to DCM and the rest of the FAP can be partitioned among other applications. The energy storage characteristic functions are derived from tables, which can be represented as heat maps shown in FIG. 6. The output of the asset/health model is the lifetime performance profiles. The tables in FIG. 6 with charge and discharge on the axes show efficiency (round trip), effective capacity, and capacity fade which are also functions of temperature, voltage range, and calendar life. Raw battery data is generated from operations of the energy operating system. This data is compared to the SLCD in order to update the model. FOPs are modeled with the SLCD to forecast efficiency losses, operational performance, and degradation. The output of this model can be used, in an iterative process, to modify and optimize the FOP. The SLCD was originally designed with ESS in mind; however, because it essentially measures lifetime efficiencies, degradations, and limitations, it can be used with other types of energy assets, such as HVAC or generators. Predicting how a particular ESS ages as a function of use is critical to de-risk the financing of energy storage applications.
As noted, given the charge and discharge rates of the ESS (battery), along with temperature, voltage range, calendar life, etc., the model generates energy storage characteristic functions including efficiency, effective capacity, and capacity fade.
In one embodiment, the effects of other applications on an asset can be used to create the predictive analytics package in a feedback loop. The difference between the prediction, derived from the modeling, and the actual operational performance of the asset is used to update the model. After each model update the application profile and FOP are re-computed. This can be characterized as a continuous correction, that is, in real-time, updating the behavior of an energy asset.
FIG. 4 is a block diagram showing components and data streams in accordance with one embodiment, most of which have been described above, but are shown together here. The primary component 402 contains a predictive analytics module 404 that creates, in part, predictive analytics package 316 which is transmitted via a suitable communications means to aEOS 302. The modeling component is comprised of three modeling modules: application performance 406, asset/health 408, and economic 410. Inputs to module 402 include historical data of the energy asset users, such as bills, smart meter data, and other customer data. The other input to module 402 includes SLCD 414 which is created in part from deltas derived from asset profiles 314. The result of the modeling is FOPs/FAPs that are used together with the modeling to create predictive analytics package 316. Also shown is an FOP/FAP server 420 similar to the one shown in FIG. 3. It accepts as input FOP for service/application 416 and FAP for asset 418.
In one embodiment, a device/asset FAP is calculated to fulfill an application/operation FOP and both profiles are contained in the predictive analytics data package. As noted, working in conjunction with aEOS is a FAPs/FOPs method and server. It can operate as a remote server (in the cloud) or locally with the energy assets and eACS, or anywhere in the network. In one embodiment, an FAP contains at least three features in a “behind the meter” example: power (kW), amount of energy used in future (Kw/h), and economic function or indicator ($), which likely contains a variety of factors and may function as a tuning parameter. An FOP has a power profile as well as an economic profile.
In the battery or ESS embodiment, the predictive analysis and the operations profile may be used to ensure or check ESS warranty compliance, and automatically alert the operator in the event of aberrant behavior. In another use case, the data may be helpful in checking financial compliance of the ESS or other asset.
In one embodiment, an asset is calculated to have a forward availability profile (FAP). It should also be noted that multiple assets will each have their own FAP and that the FAPs may be collected and indexed into an individual FAP. In one embodiment, calculations done to derive a FOP are done on an asset. During typical operation, there is one operation performed on one asset, which may have multiple applications (e.g., peak shifting, demand response, stabilization, etc.) which can be performed concurrently. This is an aspect of the co-optimization that determines the partitioning of capacity. An FOP becomes an OP or AP at energy asset runtime. This asset profile contains actual runtime data comprised of raw data that may be used to extract elements from SLCD.
FIG. 5 is a flow diagram of a process in accordance with one embodiment describing in part the process within the aEOS. At step the aEOS receives FAPs (kW, kW/h, and $) for one or more assets and FOPs (kW) for one or more energy applications or services. At step 504 the aEOS receives a predictive data analytics package which contains the models described above for application performance, asset/health, and costs. More specifically, it contains the three matrices described below, each a function of temperature, voltage range (V2-V1), and point in time in calendar life of asset. At step 506 one or more energy applications are executed by controlling an asset within the FAP according to FOP or energy application. At step 508 the aEOS collects data for an application runtime profile. At step 510 it collects data for an asset runtime profile. At step 512 the runtime data from the two profiles are compared with the three models or matrices. At step 514 the asset profile data is transformed into data that can be stored in SLDC. At step 516 the FAPs and FOPs are updated and a new (updated) predictive analytics data package is created.
FIG. 6 is a diagram showing three matrices relevant to storage life characteristic data in accordance with one embodiment of the present invention. The x-axis for all three shows charge rate (hours) and the y-axis shows discharge rate (hours). Matrix 602 shows efficiency (%), matrix 604 shows efficiency capacity (%), and matrix 606 shows capacity fade. The three variables shown in matrices 602-606 (efficiency, efficiency capacity, and capacity fade) are dimensional. The tables reveal one slice or instance through this space at a 1) specific temperature, 2) voltage range, and 3) point in calendar life. The data in tables 602-606 change resulting in new tables when the temperature, voltage range or calendar life data changes.
