Abstract: Existing researches of the comprehensive evaluation of urban power distribution network planning focus mainly on the power grid of the planning target year, ignoring other planning years. So, a comprehensive multistage evaluation method for distribution network planning is proposed. Firstly, based on existing research results, an evaluation index system, involving the superior power resources level, network structure level, load supply capacity and equipment technology level, is built. Secondly, according to the actual regional situation and development goals of the distribution network, the ideal evaluation index values are set as the comparative objects for the current situation of the distribution network and planning schemes. Finally, the whole process of the comprehensive evaluation of the distribution network planning are presented based on AHP-TOPSIS( analytic hierarchy process and technique for order preference by similarity to an ideal solution). The feasibility and effectiveness of the proposed method are verified by a case study of an actual distribution network planning schemes for an example region.
