Electric power dispatching of virtual power plant with electric vehicle

Abstract

Because electric vehicles have many advantages such as low carbon, environmental protection, and low cost compared with fuel vehicles, electric vehicles have developed rapidly in recent years, which will lead to large-scale impact load. In this paper, the electric vehicle is regarded as an energy storage device, a multi-energy VPP electric thermal scheduling model including electric vehicles is established, and a scheduling strategy for electric vehicles to participate in the power system scheduling is proposed. With the minimum cost of VPP and the minimum carbon dioxide emissions as the optimization objectives, the relevant objective functions are described, and equality constraints and inequality constraints are applied to them. Then, the improved algorithm is applied to solve the model. The results of the example analysis show that the virtual power plant system model with electric vehicles established in this paper can reduce the operating cost of the VPP system, reduce carbon emissions, and be conducive to the safe, low-carbon, and economic operation of the power system.
