本文提出了一种新的校正控制策略，可以有效地协调分布式储能和批量储能，以缓解事故后的过载。在紧急情况发生后，立即实施分布式电池，以提供快速纠正措施，以将功率流降低到低于其短期紧急额定值。在长期内，抽水蓄能机组工作在抽水或发电模式下，以帮助常规发电机组将线路流量保持在正常额定流量以下。该问题被描述为多阶段修正安全约束最优潮流(CSCOPF)。提出了一种基于Bders分解的算法来寻找最优基本情况解，并寻找可行的纠正措施来处理所有突发事件。基于改进的RTS-96系统的算例研究验证了所提出的控制策略的性能和有效性。
This paper presents a novel corrective control strategy that can effectively coordinate distributed and bulk energy storage to relieve post-contingency overloads. Immediately following a contingency, distributed batteries are implemented to provide fast corrective actions to reduce power flows below their short-term emergency ratings. During the long-term period, Pumped Hydro Storage units work in pumping or generation mode to aid conventional generating units keep line flows below the normal ratings. This problem is formulated as a multi-stage Corrective Security-constrained OPF (CSCOPF). An algorithm based on Benders decomposition was proposed to find the optimal base case solution and seek feasible corrective actions to handle all contingencies. Case studies based on a modified RTS-96 system demonstrate the performance and effectiveness of the proposed control strategy.
