New energy power generator credit evaluation method and device, equipment and storage medium

Abstract

The invention discloses a new energy power generator credit evaluation method and device, equipment and a storage medium. The the method comprises the following steps: constructing a multi-dimensional index system based on big data of a new energy power generator, wherein the multi-dimensional index system comprises a basic credit index, a market transaction credit index, a reward index and a punishment index; carrying out index weighting on indexes in a credit evaluation index system, and determining weight calculation strategies of each index; solving index weights of each dimension according to the weight calculation strategies of each index, and constructing a fuzzy evaluation matrix; according to the index weights of each dimension and the fuzzy evaluation matrix, calculating a comprehensive evaluation vector of new energy power generator credits, and determining a credit rating of the new energy power generator credits. According to the method, the accuracy of evaluating the new energy power generator credits is improved, the pairwise comparison process is greatly simplified, and the related research of the existing power market subject credit evaluation is enriched.

Description

technical field [0001] The invention relates to a credit evaluation method, device, equipment, and storage medium for new energy power generators. Background technique [0002] New energy generally refers to renewable energy that is developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, and tidal energy. In addition, there are hydrogen energy, etc.; coal, oil, natural gas, water energy, nuclear fission energy and other energy sources that have been widely used are called conventional energy sources. New energy power generation is the process of using existing technologies to realize power generation through the above-mentioned new energy sources. [0003] Wind power and solar power generation projects are effective means for my country to achieve the goal of carbon neutrality. In 2021, the total scale of new generating units may exceed 120 million kilowatts, which wi...

However, in the context of accelerating investment in the industry, it is necessary to focus on the risks of power companies investing beyond their own capabilities and operating management

[0004] However, compared with conventional power generators, there are certain differences in the credit measurement of new energy power generators in the electricity market: First, there is no need to consider the emission of pollutants in the power generation process and the power generation efficiency of fuel; second, new energy power generators Participate in medium and long-term power transactions and spot power transactions at the same time; third, the output of new energy power generators has great uncertainty, so it is necessary to focus on the accuracy of their market transaction declarations
