Operational risk assessment of power system with large-scale offshore wind power under typhoon weather
The strong randomness of typhoon is easy to cause violent fluctuation of offshore wind power output,which brings new challenges to the operational risk assessment of power system under large-scale offshore wind power integration. Therefore,an operational risk assessment of power system with large-scale offshore wind power under typhoon weather is proposed. Considering the prediction effect of several typhoon prediction agencies,a generation model of wind power output scenarios based on multiple error distribution-condition-deep convolution generative adversarial network(MED-C-DCGAN) is constructed. By introducing the regular term constraints,the statistical characteristics and time series characteristics of output errors under different prediction timeliness are reflected,and the generation accuracy of output scenarios is improved. The AC/DC power system model with large-scale offshore wind power is constructed,and the probabilistic power flow algorithm of AC/DC system based on interval constrained Gaussian mixture model(IC-GMM) is proposed. By interval constraints on the diagonal elements of the covariance matrix,the deviation of pro-babilistic power flow calculation results caused by the violent fluctuation of output during typhoon is avoided. The system risk is quantified by the comprehensive risk indicators reflecting voltage out of limit and line overload to improve the accuracy of risk assessment results. The effectiveness of the proposed model and method is verified by case study simulations.
