The invention discloses a comprehensive evaluation method for an electric power spot market. Firstly, starting from the principle of the electric power spot market, the principle of index selection isdetermined, including six aspects of comprehensiveness, conciseness, feasibility, comparability, guidance and emphasis. Meanwhile, based on consideration of a complex system, a hierarchical index system is selected as a basic framework of the evaluation system. Then, a plurality of groups of weight coefficients are obtained by adopting a plurality of weight assignment methods such as an expert scoring method, a correlation coefficient analysis method and an entropy evaluation method based on an analytic hierarchy process, and the comprehensive weight coefficient of each index is determined byutilizing a comprehensive weight assignment method based on a game theory; and finally, the market is comprehensively evaluated by using a grey relational degree analysis method according to the greycharacteristic of the electric power spot market. The method plays an important role in scientifically analyzing the operation condition of the electric power market, finding out existing problems and predicting the market development trend, thereby promoting healthy and orderly development of the electric power spot market.
Description
technical field [0001] The present invention relates to the technical field of electric power market, and more specifically, relates to a comprehensive evaluation method of electric power spot market. Background technique [0002] The electricity spot market refers to a trading market that uses electricity as a commodity for real-time or quasi-real-time transactions. Optimize the allocation of social resources to obtain greater social benefits. [0003] Foreign countries began to carry out power market reforms in the 1990s. Electricity market reforms were first carried out in Western Europe, and then extended to some power companies in the United States and Oceania. As of 2009, 86.49% of the global population has undergone power market reforms, and the combined GDP of countries with power market reforms accounts for 94% of global GDP. At present, the mature power trading markets in the world mainly include the PJM power spot market in the United States, the Nordic power m...
