Research on the Risk Resilience Assessment of Distribution Network Under Typhoon Weather
Aiming at the defects of unreasonable load weight distribution and low evaluation accuracy in the current assessment of distribution network resilience,a distribution network resilience assessment model based on Monte Carlo method is pro-posed.Taking typhoon as an example,a quantitative model of the impact of extreme weather events is established.The whole process of extreme weather is simulated based on Monte Carlo method,so as to generate the fault scenario under extreme weather events.A multi-objective optimization algorithm of load loss based on PSO is proposed to solve the resilience index of distribution network system according to the comprehensive load loss.In the experiments,the influence of extreme weather e-vents on distribution network is analyzed by IEEE33 bus system.The results show that the performance of the proposed basic model after the optimization of the improved PSO algorithm is significantly better than other methods,and the assessment accu-racy is 0.9575.The simulation results further verify that the proposed model can be used as a reference for the assessment of distribution network resilience.
