Research and Application on Matchmaking Tradeoff Competition Mechanism Design in South China Power Market

There are two difficult problems should be solved during designing practicable regional transaction model, one of them is to design a rational transaction mechanism to ensure the electricity prices of different provinces in the region are relatively stable, so the balanced economic development of these provinces can be coordinated to implement the harmonious development in both power industry reform and social market economy; and the another one is that some practical problems, such as the power transmission cost for cross-provincial transaction should be impartially and properly solved. On the basis of detailed research on above-mentioned problems, this paper presents a new matchmaking tradeoff competition mechanism design in electricity market which used to be in security and stock market. Based on theoretical analysis, trade procedure and example in South China Power Market are also introduced, which can supply a theoretical reference for the competition mechanism design in regional electricity market.
