Cooperative Operation and Profit Distribution of Virtual Power Plant

Abstract

With the widespread development of distributed generation equipment, the stable access of renewable energy and the consequent energy consumption is still a concern. Virtual power plant (VPP) provides a new solution for access and consumption of renewable energy. The distributed wind turbines, photovoltaic generators, fossil power generators and energy storage equipment are taken as the research objective, and the overall economic optimization model of multi generating units in the VPP mode is established. And then Shapley value method (SVM) is used to allocate the total profit of each unit under the cooperative operation of VPP. A security pool mechanism is proposed to improve the stability of VPP, and the ways to evaluate the stability level of VPP and the contribution of VPP members are given. The simulation results show that the information of power grid will be transmitted efficiently under the cooperative operation of VPP, which can improve the utilization efficiency of energy storage equipment and reduce the rate of “abandoning wind and light” to increase the total profit distributed by SVM. The proposed security pool mechanism can effectively strengthen the stability of VPP.
