Research on Site Selection and Protection Configuration of Distributed Power Supply in Microgrid System

Distributed generation provides a new opportunity for modern power supply, and also challenges the safe operation of the existing power system. This paper studied on site selection and protection configuration of distributed power supply in microgrid system, mainly including the objective function and constraint conditions of distributed power source siting in microgrid system, the revision of distributed power source location objective function and the protection configuration principles and methods of microgrid and system access point. The results can provide technical support for planning and protection configuration of microgrid access system, and ensure the orderly development of microgrid planning and construction.
