  • the method enables private entities to cover their energy consumption with as little carbon dioxide emissions as possible. Especially after an independent energy management can be operated and thereby a precise coordination between the energy consumer and the energy sources, as well as the energy storage can take place. This allows the reduction of carbon dioxide emissions through demand-driven resource planning in the first power grid.
  • the first power grid maybe independently operable from the second power grid. This may refer to the aspect that the elements of the first power grid are not controlled by any means of the second power grid. Hence, there may be a need for said control means to control the first power grid.
  • the renewable energy source, the energy storage, the non-renewable energy source, the distribution network, and the interface to the second power grid may be independently operable from the second power grid. Thus, they may be controlled by the control means that may be comprised by the first power grid.
  • the first power grid being independently operable from the second power grid has the advantage that in the first power grid an independent energy management can be operated and a precise coordination between the energy consumer and the energy sources, as well as the energy storage can take place. This allows the reduction of carbon dioxide emissions through demand-driven resource planning in the first power grid.
  • the method may further comprise the steps of estimating a ratio of renewable electric power to non-renewable electric power provided by the second power grid, and based on this ratio adjusting a ratio of the supplied electric power P3 to the supplied electric power P4.
  • the ratio of renewable electric power to non-renewable electric power provided by the second power grid may be estimated by considering a variety of different factors singularly or in combination with each other.
  • a first factor may be the weather. For example, if wind and/or a low cloud cover is detected, a high ratio of renewable to non-renewable energy may be derived.
  • a second factor may be the time of day and/ or the season. For example, in the northern hemisphere, less solar insolation can be assumed during the winter months, so that a low ratio of renewable to non-renewable energy may be derived. Moreover also during nighttime, a low ratio of renewable to non-renewable energy may be derived.
  • a third factor may be the price called for energy from the second power grid. Since renewable energy sources regularly provide electric energy at lower cost than non-renewable energy sources, a high price called for energy from the second power grid may hint at a low ratio of renewable to non-renewable energy. The third factor may be of particular relevance if the price called for energy from the second power grid is determined by merit order, as for instance in Germany.
  • the different factors may be combined. For instance, if no wind is detected during nighttime and the price called for electric energy from the second power grid is relatively high, a low ratio of renewable to non-renewable energy provided by the second power grid is estimated.
  • Adjusting the ratio of the supplied electric power P3 to the supplied electric power P4 may refer to the aspect that the electric power P4 does not only serve to cover the difference between the electric power consumption P and sum of the electric power Pi, the electric power P2, and the electric power P3. Rather, the amount of the supplied electric power P3 may be decreased, whereas the amount of the supplied electric power P4 is indirectly proportional increased.
  • the above-described further method steps of estimating and adjusting have the advantage that in the first power grid it is possible to react to the energy mix provided by the second power grid.
  • the method further enables private entities to cover their energy consumption with as little carbon dioxide emissions as possible. This is explained in more detail below.
  • the ratio of the supplied electric power P3 to the supplied electric power P4 is optionally decreased if the estimated ratio of renewable electric power to non- renewable electric power provided by the second power grid is relatively low.
  • the estimated ratio of renewable electric power to non-renewable electric power provided by the second power grid may be referred to as being “relatively low” or “low” if a predetermined threshold value is undershot.
  • the non-renewable energy source supplying the electric power P4 is a combined cycle power plant and the non-renewable energy sources of the second power grid are primarily based on coal, decreasing the ratio of the supplied electric power P3 to the supplied electric power P4, if the estimated ratio of renewable electric power to non-renewable electric power provided by the second power grid is relatively low can contribute to reduced carbon dioxide emissions.
  • the above-mentioned predetermined threshold value may depend on the estimated ratio of renewable electric power to non-renewable electric power provided by the second power grid and the efficiencies of the non-renewable electric power sources of the first and the second power grid.
  • decreasing the ratio of the supplied electric power P3 to the supplied electric power P4 if the estimated ratio of renewable electric power to non-renewable electric power provided by the second power grid is relatively low may contribute to reduced carbon dioxide emissions, at least in the first power grid.
  • supplying the electric power P2 of the energy storage to the electricity consumer may be limited if a state of charge of the energy storage is below a predetermined threshold value and/or during predetermined times.
  • Limiting supply of electric power P2 to the electricity consumer if a state of charge of the energy storage is below a predetermined threshold value can ensure that at times when the second power grid regularly provides power that comes from non-renewable sources, less power needs to be drawn from the second power grid, for example at night. Further, limiting supply of electric power P2 to the electricity consumer if a state of charge of the energy storage is below a predetermined threshold value can ensure that fluctuations of the renewable energy source, e.g. caused by wind lulls and/ or interruptions in irradiation, may be compensated. Hence, carbon dioxide emissions may be further minimized.
  • limiting supply of the electric power P2 to the electricity consumer during predetermined times may exemplarily avoid that before nightfall the energy storage is empty and a lot of electric power coming from non-renewable sources must be drawn from the second power grid during nighttime. Thus, carbon dioxide emissions may be minimized.
  • the predetermined times may depend on solar insolation.
  • the method may further comprise the step of supplying an electric power Pio of the renewable energy source to the energy storage if a total power of the renewable energy source exceeds the electric power consumption P, and/ or if the supply of electric power Pi of the renewable energy source to the electricity consumer is limited.
  • the first power grid is thus able to store surplus energy. This allows the use of electricity produced with non-renewable energy to be avoided, e.g. during nighttime.
  • internal transmission constraints in the first power grid can be compensated, ensuring the self- sufficiency of the first power grid.
  • the method may further comprise the step of supplying an electric power Pn of the renewable energy source to the second power grid if a total power of the renewable energy source exceeds the electric power consumption P and/or if the energy storage has no further capacity. It is understood that this can contribute to a better carbon footprint of the entire power system. Furthermore, supplying an electric power Pn of the renewable energy source to the second power grid allows for a further balancing option in the first power grid which can increase stability.
  • the second power grid is a public power grid, wherein the first power grid further optionally is a private power grid.
  • a public power grid according to the present disclosure is operated by a DSO (Distribution System Operator).
  • a private power grid within the meaning of the present disclosure is not operated and maintained by the same DSO as the second grid, i.e. the public power grid.
