考虑次生故障差异化影响下韧性主动提升的输电系统网架重构策略
A Novel Transmission Network Reconfiguration Strategy Considering Active Improvement of System Resilience Under the Differential Influence of Contingencies
摘要
Abstract
In recent years,the green-oriented transition of energy has accelerated,extreme events have occurred frequently,and the international situation has been unstable.With the coexistence of conventional and unconventional security risks,the risk of power system outages increases.A robust and reliable network reconfiguration strategy is important to prevent the recurrence of collapse during restoration.Secondary faults or contingencies are rarely considered in the existing research on power system restoration.In view of that,this paper proposes a novel network reconfiguration strategy with active improvement of system resilience that considers the differential impact of contingencies.First,the necessity of considering the impact of contingencies in transmission network reconfiguration is discussed.Then,based on Partitioned Multi-Objective Risk Method(PMRM),a novel resilience index is proposed to differentiate contingencies and highlight the impact of high-risk failures.Then,a global optimization model for network reconfiguration considering the active improvement of resilience is established,which improves the resistance to high-risk contingencies.In order to improve the solution efficiency,a practical solution strategy based on the window rolling mechanism is proposed,which can provide a network reconfiguration scheme that considers both rapidity and robustness.The effectiveness of proposed method is verified by the IEEE 39-bus and IEEE 118-bus system.关键词
