摘要

为增强电力系统的灾害抵抗能力，对新能源高占比电网灾前中短期及临近期的主动预防策略进行了研究。首先，结合灾害预测的准确度及主动预防措施的时间尺度，研究了灾前主动预防决策窗口长度。其次，构建了以调度代价与失负荷损失之和最小为目标的预防-攻击-预防三层主动预防模型：上层模型决策移动应急电源接入位置和接入时间；中层模型基于自然灾害场景集确定失负荷损失最大的极端灾害攻击场景；下层模型在移动应急电源接入方案和极端灾害攻击场景的基础上，计及组网约束优化网络拓扑结构和电源出力。最后，在IEEE 69节点算例系统上对方法的有效性进行了验证，结果表明：采取主动预防策略的预防代价远远小于被动防御措施，且移动应急电源预接入时间也对主动预防策略的预防代价有一定的影响。

Abstract

In order to enhance the disaster resistance ability of power system， the active prevention strategy of the power grid with high proportion of new energy before disaster is studied. Firstly， combining the accuracy of disaster prediction and the time scale of proactive preventive measures， the length of proactive preventive decision window before disaster is studied. Secondly， a three-layer proactive prevention model with the goal of minimizing the sum of dispatching cost and loss of load is constructed. The upper-layer model determines the access location and time of mobile emergency power supply， while the middle-layer model determines the extreme disaster attack scenario with the greatest loss of load based on the set of natural disaster scenarios. The lower model optimizes the network topology and power output based on the mobile emergency power access scheme and extreme disaster attack scenario. Finally， the effectiveness of the proposed method is verified on the IEEE 69-node simulation system. The results show that the preventive cost of the active preventive strategy is much less than that of the passive preventive measures， and the pre-access time of the mobile emergency power also has a certain impact on the preventive cost of the active preventive strategy.
