基于风险评估的电力系统连锁故障协调控制模型
Coordinated Control Model of Power System Cascading Failures Based on Risk Assessment
摘要
Abstract
By analyzing the coordination between preventive control and blocking control of cascading failures,a coordinated control model based on risk assessment is proposed for power system cascading failures in terms of reducing the risk of blackout.First,the risk of cascading failure is solved by considering the failure of lines,power flow transfer,hidden failures, and weather factors.Then the coordinated control model is expressed as an optimization problem based on risk indices. Besides,the coordinated control model also considers the position of blocking control, which is confirmed by the risk importance of faults.Finally,the example analysis shows that the model can effectively coordinate the preventive control and the blocking control and provide the control scheme with the highest cost performance under different weather conditions. Compared with the pure preventive control and blocking control,the scheme is able to meet the demand of security and economy,while provide a reference for decision-making of defense.关键词
