Abstract: As an effective carrier for new energy to participate in the electric energy market, the advanced market mechanism and the strategy of controlling flexible resources have become the key problems that need to be solved. Based on this, this paper proposes the joint market optimization strategy of virtual power plant energy and peak regulation considering the differentiated quotation mechanism of power supply equipment, and carries out the participation market behavior of virtual power plants including new energy. Firstly, based on carbon trading, green certificate trading and demand response, a differentiated quotation mechanism for different power supply equipment in virtual power plant is proposed to reasonably guide virtual power plant to participate in the market optimization; secondly, to realize the privacy of the quotation information of each equipment; finally, double-layer model with joint optimization formula and CPLEX solver to verify the effectiveness and practicability of the proposed method and model in different environments. The simulation results show that the proposed differentiated quotation mechanism reduces the joint operation cost, with a maximum reduction of 50.34%, and effectively coordinates the interest relationship between the virtual power plant and the joint market.
