Combine the charging application of tou power price and electric automobile, make full use of the time of staying in parking lot for the electric automobile, rationally
Arrange charge power and charging interval.Effectively reduce the total power supply cost of system, realize most optimum distribution of resources, indirectly mitigate simultaneously
Environmental pollution, promotes energy-saving and emission-reduction, improves comprehensive energy utilization rate and system economy.Appearance is not had to be based in domestic market
The Demand-side distributed system energy management method that electric automobile is actively applied for and electricity price is followed the tracks of, existing management method cannot be right
Charging electric vehicle load is shifted, and cannot be by the regenerative resources such as photovoltaic generation, wind-power electricity generation and tou power price information
Combine, its energy management cannot give full play to technical advantage and the economic advantages of distributed energy and tou power price.Thus, this
Invention is complied with the market demand and has been filled up the energy management system field blank that electric vehicle charging mode and electricity price are followed the tracks of.
