Virtual power plant VPP is a special power plant that aggregates distributed equipment such as distributed generators energy storage systems controllable loads and electric vehicles through advanced information and communication technology and software systems and then participates in the operation of power market and power grid coordinately. Aiming at the difficulty of wind power and photovoltaic participating in large power grid and preferential consumption in the renewable energy industry at the present stage a VPP scheduling strategy considering supply and load transfer is proposed based on the characteristics of strong communication and high aggregation of VPP. The optimal overall profit of the VPP is considered as the objective function the scheduling flexibility of the VPP is strengthened from the supply side and the demand side at the same time. Supply transfer is realized through energy storage equipment battery energy storage system and hydrogen energy storage system are considered to participate in scheduling at the same time giving full play to their energy storage advantages. Load transfer is realized by flexible load and all flexible loads are divided into short-term medium-term and long-term to reflect the actual situation where the classification is based on the load of flexible load and the latest dispatching time. The simulation results show that the participation of energy storage equipment and flexible load can significantly improve the robustness of VPP operation enhance the consumption level of new energy achieve the effect of ??peak shaving and valley filling and have a good economic performance.
