Research on Evaluation Model of Full Voltage Level Operation Efficiency of Provincial Power Grid Using Analytic Hierarchy Process (AHP)

摘要

Considering the deepening of electric power market reform, it is urgent to analyze the operation efficiency of the full voltage level of provincial power grids, of different cities. And then, to seek the cities with lower operation efficiency, which will give guidance to the accurate investment of power grids and enhance the comprehensive investment benefits. This paper established an evaluation model of full voltage level operation efficiency of provincial power grid, and an evaluation index system of sub-voltage level operation efficiency of provincial power grid. Using analytic hierarchy process (AHP), the weights of evaluation indexes have been determined, and the evaluation results of power grid operation efficiency in different cities have been obtained. Finally, according to the scores, the cities with low operation efficiency were determined, and the specific indices of the cities with low operation efficiency were analyzed to guide the investment planning of the power grid.
