The study of power grid emergency capacity evaluation method based on Fuzzy Analytic Hierarchy Process

Abstract

When the power grid encountered the strong external force, there will be a large area of power failure phenomenon, and now the corresponding emergency response measures rarely. Based on this, this paper presents a method of evaluating the emergency capability of power grids based on the fuzzy analytic hierarchy process (AHP), which aims to study the level of emergency capability of current power grid and find its weak links to improve and improve the stability of power system. Firstly, based on the actual situation of China's power grid enterprises, determine the evaluation index system. Secondly, the corresponding index weights are calculated by the analytic hierarchy process. Finally, according to the weight distribution, the fuzzy evaluation of the power system emergency system is carried out to determine the emergency ability. And according to the actual situation of enterprises, carrying out the simulation, the results verify the validity of the proposed method.
