Multi-objective optimal scheduling method for Regional Photovoltaic-Storage-Charging Integrated system Participating in Demand Response

摘要

With the development of photovoltaic power generation and the popularity of electric vehicles, the integrated system of regional photovoltaic-storage-charging emerges as the times require. In this paper, the optimal scheduling problem in the operation of photovoltaic-storage-charging integrated system under the condition of grid connection is studied. This paper introduces the structure, basic composition unit and operation strategy of optical storage and charge integrated system under time-sharing electricity price. Considering the demand response of the charging load of the electric vehicle and the basic electric load of the village area, the transferable load of the peak and trough of the electricity price is determined. A two-objective optimization model is established to reduce the load peak and valley difference and improve the economy of the integrated optical storage and charging system, and the NSGA-II algorithm is used to solve it. Finally, an example is given to prove the effectiveness and feasibility of the proposed model and algorithm.
