Construction prospect analysis of regional reserve market and joint clearing analysis of spot market and reserve market

The construction of regional electricity market in China is progressing steadily, but the research on regional reserve market in China is still lacking. Therefore, this paper first calculates the bidding prices of generators in reserve market based on the clearing results of the spot market, then establishes a clearing model for regional reserve market, and finally builds a joint spot-reserve clearing model incorporating the constraints of both spot market and reserve market. Based on actual data of a four-province region in China, this paper analyzes the prospects for building a regional reserve market and the potential of the joint spot-reserve clearing method. The results show that the establishment of the regional reserve market can alleviate the system's lack of reserves and reduce the system reserve cost. The joint clearing method can greatly improve the adequacy of system reserve capacity and reduce the total cost of the system.
