Aiming at the problems of low power supply reliability, poor transfer capacity between stations, and low line utilization in the current distribution network, this paper proposes a diamond-shaped distribution network structure with a clear structure. First, we investigated the typical wiring patterns of medium-voltage distribution networks in Tokyo, Japan, Paris, France, and China’s developed cities, and summarized experience and shortcomings. Secondly, combining the typical wiring patterns of distribution networks in China and abroad, construct a diamond-shaped distribution network structure, and study its adaptability, safety and flexibility, power supply reliability, and economy. Finally, take the transformation of the wiring mode of a regional distribution network in a certain city as an example, compare the use of the diamond-shaped distribution network structure in this article with the use of cable double-ring network wiring, cable “double petal” wiring, and Shanghai diamond-type wiring distribution network grid reconstruction The effect verifies the superiority of the diamond-shaped distribution network structure in this paper.

Supply Reliability

The impact of PV and Battery storage system on the power supply reliability of distribution network is great. Firstly, the assumptions of the battery storage operating strategy are given, and four typical evaluation indexes are presented. Then, the impacts of different PV peak active power, different battery capacity and PV & Battery Storage on the power supply reliability are discussed. Finally, the impacts of PV, Battery and PV & Battery on the power supply reliability of distribution network are compared and analyzed. These results are provided as references for the optimal capacity configuration of PV & Battery.
