Aiming at the lack of a systematic research method on the distribution of ring station in the existing 10kV urban medium voltage distribution network research, a method of ensuring the location and capacity of ring station based on the weighted Voronoi diagram is proposed. First, analyze the location and capacity of ring station based on the structure of the urban medium-voltage distribution network; Second, in view of the location and capacity of the ring station of the urban medium voltage distribution network, the line investment of the upper-level to the ring station, the investment cost of the ring station, and the line investment of the lower-level to the ring station are comprehensively considered, and build the mathematical model. Third, a method of ensuring the location selection and capacity determination of ring station based on weighted Voronoi diagrams and a solution process are proposed. Finally, an example is used to verify the effectiveness and practicability of the proposed method.
