A Method for Comprehensively Evaluating the Acquisition Capability of Low-Voltage Distribution Network Station Area

With the promotion of smart grid construction, the focus of grid development shifts from transmission network to distribution network. Adopting the comprehensive evaluation method can accurately reflect the acquisition capacity of the station area and the satisfaction of each indicator, which helps to screen the problematic station areas from a large number of low-voltage distribution network station areas. In order to assist the power company to efficiently select the inferior station area from many low-voltage distribution network station areas, and propose a corresponding transformation plan for the problem station area, this paper proposes a low-voltage distribution network station area acquisition capability evaluation method. Firstly, a comprehensive evaluation indicator system for the acquisition capacity of low-voltage distribution network is established. Then, the CRITIC method and the Improved Analytic Hierarchy Process (IAHP) are used to determine the objective weight and subjective weight of the indicator respectively, and the comprehensive weight is obtained by combined calculation. Finally, a comprehensive evaluation model is constructed to evaluate the acquisition capacity of the station area. The case analysis of a certain place in Zhejiang shows that the comprehensive evaluation method proposed in this paper can effectively evaluate the acquisition capacity of the station area.
