A Layout Evaluation Method for Source-Network-Load-Storage and Multi-energy Complementary Projects Based on Entropy Weight and Delphi Method

Source-network-load-storage integration and multi-energy complementary is of great significance for accelerating the construction of new power systems, achieving high-quality development of the power system, improving the coordination and mutual aid ability of multiple energy sources, and promoting China's green and low-carbon energy transformation and economic and social development. Firstly, based on an analysis of such factors as the national resource elements for integration and complementary, national development strategy, load development, electricity price level, new energy consumption conditions and regulatory capacity demand, a subjective and objective combination weighting evaluation system is established. And then, the entropy weight method is used to determine the objective weights of the influencing factors for each development route of integration, and the Delphi method is used to determine the objective weights. Through fusion calculation, the comprehensive weights of the influencing factors are obtained. Based on the scores and weights of the influencing factors, every development route is scored, and the development priority levels are divided. Finally, the construction priority order for integration projects in all provinces across the country is obtained, which can provide a technical support for the development of the integration projects in all provinces.
