Abstract:

Virtual power plant (VPP) technology is an effective way for renewable energy grid-connecting, and is helpful for demand-response resources such as flexible load and electric vehicle to participate in power market. This paper analyzes the characteristics, rights and responsibilities of each member in the virtual power plant,draws up the call contract based on price elasticity for each member, and designs the day-ahead and real-time power market transaction process including main energy and auxiliary services. According to the conditional value-at-risk (CVaR), the risk aversion model of virtual power plant is established, the Shapley value and marginal expected shortfall (MES) of each member are quantitatively analyzed, and the internal benefit distribution method of virtual power plant is given. An example shows that the virtual power plant can take care of the interests of all parties. Also in the example, this paper quantitatively analyzes the risk benefits under different market strategies. The results show the effectiveness of the proposed method.

Key words: power market, virtual power plant(VPP), conditional value-at-risk(CVaR), Sharply value, marginal expected shortfall(MES)
