Research on Evaluation of Power Grid Investment Capability Based on TOPSIS Method

With the rapid development of China's national economy and the continuous improvement of people's living standards, the demand for electricity is increasing day by day; the investment scale of the power grid is also increasing. In order to evaluate the investment capacity of power grid scientifically, this paper constructs the evaluation index system of grid investment ability from five aspects: grid operating efficiency, grid operation efficiency, grid safety, coordination of power grid development and social environmental benefits, and constructs the TOPSIS comprehensive evaluation model on the basis of the weighted the order relation method. Finally, this paper uses examples to make an empirical analysis on the comprehensive evaluation of the investment capacity of the grid, and explores the reasons for the poor investment capacity of the power grid in individual year and puts forward relevant suggestions.
