Index evaluation of distribution network based on improved analytic hierarchy process
Based on the traditional distribution network evaluation system, this paper fully considers the environmental effects of a large number of distributed power sources connected to the distribution network, and establishes a new energy distribution network index evaluation system that considers environmental protection. The evaluation system includes the environmental protection indicators such as the proportion of clean energy generation and the reduction of pollution gas emissions which are different from the traditional distribution network assessment system. Aiming at the problem that the traditional analytic hierarchy process adopts a single weight calculation method and the weighting difference is different due to different method selection, an improved analytic hierarchy process is proposed to index the new energy distribution network. The improved analytic hierarchy process adopts geometric average method, arithmetic average method, eigenvector method and least square method to calculate weights and take the average value instead of a single method to calculate the weight. The calculation of two areas in the distribution network of a coastal area in Guangdong verifies the rationality of the proposed index evaluation system and the effectiveness of the proposed algorithm.
