User-side distributed optimal control method for virtual power plant with demand response

There are many distributed energy devices on the user side, including solar photovoltaic, wind power generation, energy storage equipment, etc. Each device has different characteristics and states, and they are difficult to control. Therefore, a user-side distributed optimal control method for the virtual power plant with demand response is proposed in this paper. The operation structure of the virtual power plant (VPP) is analyzed, and the user-side demand response model is constructed. Based on this, the consistency algorithm is introduced to construct the VPP power distribution model and realize the distributed optimization control of the user side of the virtual power plant. The experimental results show that the proposed method can calculate the power control amount of VPP in different running periods, and the calculated results are in good agreement with the control command curve of the power grid. After the reactive power is allocated, the reactive power fluctuation coefficient of each node in the VPP is less than 0.1. Under the application of the research method, the battery generates electricity when the distributed power supply of the virtual power plant is in a low state, which can meet the demand of the load side of the virtual power plant.
