摘要/Abstract

摘要：

关键输电通道辨识及强化是电力系统抵御台风等极端灾害的有效手段。为此，提出了面向抗灾能力提升的两阶段强化方法。首先，基于复杂网络理论和系统状态分析，提出了加权网架熵和潮流转移熵的关键通道辨识指标；然后，结合台风Batts模型计算风场内实时风速，利用蒙特卡洛模拟法对不同风速下通道可用状态采样，构建用于输电通道强化的故障场景；在此基础上，提出两阶段输电通道强化方法，第一阶段以加固、负荷损失等成本之和最小为目标，考虑通道强化、发电机出力调整等措施，第二阶段考虑网架拓扑完整程度，以功率可达性为目标进一步优化输电通道强化策略。研究表明：所提方法能统筹考虑网架拓扑及系统状态变化，实现关键通道准确辨识及系统韧性提升。

Abstract:

Identification and reinforcement of critical transmission corridors is an effective measure for power systems to defend against extreme disasters, such as typhoon. Therefore, a two-stage reinforcement method for disaster resilience enhancement is proposed. Firstly, key corridor identification indices, including weighted grid entropy and flow transfer entropy, are introduced based on complex network theory and system state analysis. Secondly, the Batts typhoon model is used to compute real-time wind speeds, followed by Monte Carlo sampling of corridor availability under different wind speeds, generating failure scenarios for transmission corridor reinforcement. On this basis, a two-stage transmission corridor reinforcement method is proposed. Stage 1 aims to minimize the sum of costs such as reinforcement and load loss, considering measures like corridor reinforcement and generator output adjustment. Stage 2 takes into account the integrity of the grid topology, further optimizing the transmission corridor reinforcement strategy with the goal of power accessibility. The study shows that the proposed method integrates both the topology and changes in system state, thus achieving the accurate identification of critical corridors and enhancing system resilience.
