| Abstract: | In order to analyze the impact of extreme weather processes such as typhoon and rainstorm on the normal operation of the power grid and make risk assessments to deal with it , a power grid fault early warning and risk assessment model under extreme weather processes is proposed.The reliability performance and risk assessment of the power grid under the influence of extreme wind and lightning weather processes are analyzed , and the impact of extreme meteorological environment on the power system is analyzed.The grid fault assessment model under extreme weather conditions is established , and the grid resilience index is proposed.The ensemble is analyzed for reliability assessment , in which artificial neural network is applied for power flow calculation.Finally , the effectiveness of the method proposed in this paper is demonstrated by simulation analysis. |
