Abstract

The invention relates to a game theory combined weighting-based photovoltaic power plant performance evaluation method. The method includes the following steps that: photovoltaic power plant performance evaluation indexes are selected to establish an evaluation matrix; syntropy processing and normalization processing are performed on the evaluation matrix, so that a standard evaluation matrix can be formed; an analytic hierarchy process is adopted to determine the weight vectors w1 of the evaluation indexes; an entropy method is adopted to determine the weight vectors w2 of the evaluation indexes; a game theory-based combined weighting method is adopted to determine the comprehensive weights of the indexes; and the performance evaluation value of a photovoltaic power plant is calculated according to the comprehensive weights of the indexes, and the performance detection and evaluation of the photovoltaic power plant can be realized. According to the method of the invention, the weights determined by the two different methods are integrated to the comprehensive weights of the indexes through using the game theory, and therefore, the determined weight coefficients can reflect various kinds of information simultaneously, and one-sidedness and arbitrariness of using a single method to select weights can be avoided, and comprehensive and objective evaluation basis can be provided for electric power departments in photovoltaic power plant performance evaluation.

Description

technical field [0001] The invention belongs to the technical field of new energy control, in particular to a method for evaluating the performance of photovoltaic power plants based on game theory combined weighting. Background technique [0002] In recent years, with the strong support of the governments of various countries, photovoltaic power generation, which has the advantages of cleanness, environmental protection, pollution-free, and renewable, has developed rapidly. With the change of the photovoltaic power plant construction subsidy model, that is, the original power plant construction subsidy is changed to the kWh subsidy, and users pay more attention to the power generation efficiency and power generation capacity of the power plant, which also means the level of power generation capacity and performance quality of the photovoltaic power plant. , has become the key to improving the yield of power plants and shortening the cost recovery cycle. Therefore, in order...
