Research on the evaluation model of input and output benefit of enterprise distribution network based on fuzzy membership

Based on the reform of power system, this paper establishes an indicator system for the evaluation of input and output efficiency of distribution network based on the integration of distribution and financing, and builds the evaluation model of the input and output efficiency based on the fuzzy membership degree, extract the data of the pilot units, conduct model trial calculations, optimize the model, and assist the performance appraisal of each unit, ensuring the efficiency of grid investment efficiency, strengthening precision investment, realizing investment must be effective, and inefficiency requires accountability.
