As a complex network, microgrid must have some weakness. Risk assessment of microgrid will help to find out these weakness so as to put forward the targeted improvement measures and provide strong support for the optimal operation of microgrid. According to the risk assessment of microgrid, this paper establishes a microgrid risk index system, which includes the first-level indexes and corresponding sub-indexes of structural safety, operation safety and technical safety, and innovatively establishes a credibility entropy weight coefficient evaluation model, and calculates the weight of each index layer and the comprehensive risk assessment score of the microgid. Furthermore, the risk assessment of a microgrid system is analyzed by quantitative calculation in order to make the assessment results more reliable and provide reference for further improving the risk assessment of the microgrid.
