Power System Risk Research Based on Entropy Weight Matter Element Extension Model

Abstract

With the rapid development of the national economy and the gradual improvement of people’s living standards, the demand for electric energy in various fields is constantly increasing. In order to meet the growing demand for electricity, it is necessary to increase the level of power security. Based on the characteristics of power grid projects, this paper analyzes the shortcomings of previous power grid project risk assessment methods, proposes a matter-element extension analysis model based on entropy weight method, evaluates grid project risks and introduces related functions and correlations and scalability. Finally, the empirical analysis is carried out in conjunction with a Chinese urban power grid plan. The results show that the method has strong feasibility and practicability.
