摘要
极端灾害事件频发加剧了通信失效风险,而城市配电网灾后抢修策略多将通信失效简化为固定延时,难以合理量化其影响,致使通信保障与抢修决策无法有效联动。为此,提出了一种考虑配电网故障抢修与通信布设时序耦合影响的“配电网-无线Mesh网”双网协同灾后应急抢修策略。构建基于故障点状态与交通情况的无线Mesh自组网布设模型,设计高效可靠的临时通信基站布设方案;建立计及通信状态的配电网抢修模型,制定提升配电网抢修效率的最优策略;采用滚动时域优化模型对双网协同灾后抢修策略进行迭代求解,并在改进IEEE 33节点配电网中进行仿真分析。结果表明,双网协同策略相比传统单网策略可将总抢修时间缩短1h以上,总负荷损失减少约22.07%,综合损失值降低20.95%,验证了所提策略的可行性以及有效性。
The frequent occurrence of extreme disaster events has exacerbated the risk of communication failures.However,urban distribution network post-disaster repair strategies often simplify communication failures as fixed delays,making it difficult to reasonably quantify their impact and resulting in ineffective coordination between communication assurance and repair decision-making.To address this issue,a dual-network coordinated post-disaster emergency repair strategy in power distribution network-wireless Mesh network is proposed,considering the temporal coupling effects between power distribution network fault repair and wireless Mesh communication deployment.A wireless Mesh self-organizing network deployment model is developed based on fault point status and traffic conditions to design an efficient and reliable deployment scheme for temporary communication base stations.A power distribution network repair model accounting for communication status is established to formulate optimal strategies for improving repair efficiency.A rolling time-domain optimization method is adopted to iteratively solve the dual-network coordinated post-disaster repair strategies.The simulative analysis is carried out based on a modified IEEE 33-bus power distribution network.The simulative results demonstrate that,compared with the traditional single-network strategy,the dual-network coordinated strategy can reduce the total repair time by over one hour,reduce the load loss by approximately 22.07%,and reduce the overall loss by up to 20.95%,thereby validating the feasibility and effectiveness of the proposed strategy.
