摘要：
The previous optimal dispatch models of VPP(Virtual Power Plant) only consider the economy of VPP and the obtained optimal dispatch schemes often fail to meet the security requirements of the distribution network, which may cause the problems of line over-load, node voltage over-limit and so on and affect the safe and stable ope-ration of the power system. In order to balance the economy of VPP and the security of distribution network, an optimal dispatch game model of VPP based on non-cooperative game theory is established and the stochastic programming method is applied to deal with the uncertainties of electricity price and renewable energy sources, such as wind power and photovoltaic power. The optimal results of optimal dispatch model of VPP, security model of distribution network and non-cooperative game model are compared based on the case of an eight-lead distribution network in the north of a city. The results show that, when VPP and distribution network play game in a non-cooperative way, the VPP will take a relatively conservative dispatch scheme by reducing the power generation of each aggregation unit, which will increase the profits of VPP and maintain high security of distribution network, verifying the validity and rationality of the proposed non-cooperative game model. © 2019, Electric Power Automation Equipment Press.
