Study on the whole process evaluation of new energy grid connection based on AHP-entropy weight method

Abstract

In order to promote the transformation of energy consumption structure to low carbon, in recent years, China has vigorously promoted the development of new energy and increased the proportion of new energy installed capacity in the power sector. However, due to the lack of benefits evaluation of the whole process of new energy grid connection at present, the existing project experience cannot provide reference and guidance for subsequent project construction to improve the benefits of new energy grid connection. Based on the existing operation data of the “New Energy Cloud” platform of State Grid Corporation of China, this study constructed the evaluation index system for the whole process of new energy grid-connection, and evaluated the benefits and quality of the project from the three stages before, during and after the grid-connection. The research results will be applied to the development of the evaluation module of the “new energy cloud” platform of State Grid Corporation of China, and can also provide a reference for the evaluation of the construction of new energy projects in the energy industry.
