Application Prospect and Advantages of Power Supply System Based on 20kV Power Distribution Network and Microgrid in China

Abstract:

In view of high-load density, abundant in wind power and solar energy resources and well-developed areas in the southeastern coastal areas of China, A great number of power system planning problems have emerged. This paper first analyzes the limitations of electric power supply with 10kV voltage level and the advantages of using 20 kV voltage level in distribution network, and then it introduces the status and disadvantages of regenerative energy power to be incorporated into the large grid along the southeast coast of China at present. Finally it is discussed that the advantages of establishing the power supply system based on 20kV power distribution network and Microgrid according to the new resources distribution and the existing problems of medium voltage power distribution in southeast China.
