In recent years, the large number of distributed energy sources connected to the grid has posed a great challenge to the flexibility of the power system, and the application of sharing economy to the trading of distributed energy sources can provide additional flexibility to the power system. This paper proposes a energy sharing model of virtual power plant considering battery energy storage, and establishes a master-slave game model with the virtual power plant sharing operator as the dominant player, and the producers and consumers of distributed energy and loads as the followers. The virtual power plant sharing operator aims at maximizing its own benefits to set the shared tariff, and the generators and consumers optimize their own electricity consumption according to the shared tariff. In addition, the model considers the impact of battery storage on virtual power plant energy sharing, and models its average lifetime cost into short-term costs associated with real-time operation. Finally, the simulations show that the virtual power plant sharing operator can increase its own revenue through energy sharing, it can also increase the benefits to the generators and consumers, and battery storage can reduce the burden on the grid and bring some revenue to the virtual power plant under the time-sharing tariff mechanism.
