Research on the classic power supply modes of AC/DC distribution network

Abstract

AbstractWith the rapid development of distributed generation and power electronic technology, it is a tendency to develop the DC distribution network based on the AC type. And it is an urgent need to solve the problem of reasonably planning of AC/DC distribution network. In this paper, the application scenarios of AC/DC distribution network are analyzed based on the distribution characters of power sources and loads. The basic modules are analyzed, and the DC voltage grade sequences, electric power network structure, equipment, configuration of distribution automation are proposed. Furthermore, 5 classic power supply modes are proposed according to the analyzed application scenarios. The research results provide technical reference for the future AC/DC distribution network planning and design.
