Construction method of virtual power plant based on Landscape theory

Abstract

In order to realize the reliability and economy of virtual power plant, landscape theory is applied to the construction of virtual power plant with distributed generation. Firstly, according to the complementarity of intermittent energy output of various distributed power sources, the attractive parameters between different distributed power sources are introduced, and then the matching degree and energy loss degree of the system based on panoramic theory are established. Then, considering the complex operation constraints of various distributed power sources, such as wind power, photovoltaic power, energy storage and electric vehicles, as well as the operation economy and energy loss after aggregation, a multi-objective function virtual power plant building model was constructed. In view of the complexity of the model, the model is transformed into a mixed integer linear single objective optimization model, and GAMS software is used for simulation solution. The simulation results show that the system operation cost is reduced and the output volatility is improved when the distributed power supply is aggregated into virtual power plant.
