| 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1 h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。 |

| Abstract: |
| 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 fai-lures 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. |
