Photovoltaic energy storage power station capacity configuration optimization method based on Stackelberg game

Abstract

The invention proposes a photovoltaic energy storage power station capacity configuration optimization method based on the Stackelberg game. The method gives consideration to the power demands of users and the electric charge pricing of the participation of a photovoltaic power station and an energy storage power station in an electric power market, builds a photovoltaic and energy storage income model based on the Stackelberg game, reduces the load of a power grid, and improves the capacity configuration of the photovoltaic energy storage power station. The photovoltaic energy utilization rate is improved. According to the method, a utility function is used to simulate the preference of a power consumer and a power consumption mode, a Stackelberg game model is established to analyze the strategy interaction of a photovoltaic power station and an energy storage power station in the real-time pricing of the power market, and the capacity configuration of the photovoltaic energy storage system is optimized by achieving balance through the game. Therefore, the purposes of improving the utilization rate of photovoltaic energy, reducing expenditure and increasing income are achieved.
