Comprehensive Evaluation of Coordination Development for Regional Power Grid and Renewable Energy Power Supply Based on Improved Matter Element Extension and TOPSIS Method for Sustainability

摘要

In the background of exhaustion of the traditional fossil energy sources, developing renewable energy has become a strategic choice for China to achieve energy sustainable utilization and energy security. The coordination between renewable energy generation and the traditional power grid is a problem that needs to be solved in the development of the power grid. The three sectors of power generation, transmission, distribution, and scheduling are considered comprehensively in this paper and an evaluation index system for the development of renewable energy and traditional power grid is designed. The traditional method of Technique for Order Preference by Similarity to Ideal Solution （TOPSIS） is improved using the idea of matter element extension, and mathematical model of comprehensive evaluation is constructed. Combined with the development index data of a regional power grid and renewable energy sources in Ningxia province, this paper applied the evaluation model to empirical research. The results show that the model meets the real situation of development of the regional power grid and renewable energy generation and has certain reference and promotion significance.
