Optimal Dispatching Considering the Participation of Flexible Resources on the Load Side in Deep Peak Regulation Market

With the construction of new power system in China, the shortage of peak regulation resources in China's power system and the serious dilemma of abandoning wind and solar energy have become increasingly severe. It is urgent to fully mobilize the peak regulation potential of flexible resources on the load side. In view of the situation that traditional thermal power units and flexible resources on the load side participate in the market together, the day-ahead market mechanism and optimal dispatching model considering deep peak regulation are proposed. On the basis of considering the load characteristics of virtual power plant (VPP), the market mechanism based on deep peak regulation quotation is designed. It provides a mechanism basis for flexible resources on the load side to participate in the power market and provide flexible regulation services for the power grid. And the participation of VPP has effectively reduced the market cost of deep peak regulation market. The effectiveness and applicability of the model are proved by analyzing the cases of IEEE-30 bus system and IEEE-118 bus system.
