Bidding Strategy of Virtual Power Plant for Spot Integrated Energy - Reserve Market

Abstract

Under the current situation of power market reform, virtual power plant(VPP) gathers distributed power generation to participate in power system operation and market transaction, which is a new technology to deal with the problem of distributed power grid connection. However, how to effectively participate in the spot market of VPP and how to take into account the market demand and the overall benefit of VPP are the practical problems faced by the popularization and application of large-scale VPP. In this context, combined with the current situation of China's spot market development, the spot market trading rules were established considering the participation of VPPs. Based on the characteristics of multi-agent layered control, the joint bidding optimization model of VPPs participating in the spot market was established, and the randomness of electricity price and intermittent power output in the spot market was treated by the multi-scenario method. The simulation example verified that the bidding model can provide strong support for the VPP to participate in the electricity market transaction, and analyzes the influence of intermittent power output correlation on the bidding strategy of VPP.
