| 摘要: |
| 电力系统大停电后，合理有序的恢复控制对于减小停电损失具有重要意义。以架空线路投运作为研究重构过程的切入点，提出了利用线路投运可靠性指标优化机组恢复顺序的方法。首先，针对当前重构方案线路投运风险定义的不足，提出了与停电损失评价标准相一致的严重程度指标。其次，通过网架恢复与机组投运过程的交互仿真，建立了与恢复实际更加契合的重构模拟时步框架。在此基础上，构建了以重构方案线路投运风险最小为目标的机组恢复顺序优化模型，并采用交叉粒子群算法和弗洛伊德算法对模型进行优化求解。针对新英格兰10机39节点系统的仿真结果表明，采用该方法获得的机组恢复方案在降低停电损失的同时，充分考虑可能的恢复路径备用通道，能够更加有效地应对潜在的线路投运失败情况。 |

| Abstract: |
| After a large-scale blackout, reasonable and orderly restoration is of great significance for minimizing the loss. The process of network reconfiguration is investigated specially from the point of switching in transmission lines. Taking lines’ operational reliability into consideration, a method of optimizing units’ restoration sequence is proposed. Firstly, a severity index in terms of the outage loss criteria is put forward to improve the definition of lines’ restoration risk corresponding to reconfiguration scheme. Secondly, a time-step frame of reconfiguration simulation accordant with the actual situation is established by means of interactive simulation between network reconstruction and units’ restoration. Furthermore, the model of optimizing units’ restoration sequence is constructed based on minimizing lines’ restoration risk corresponding to reconfiguration scheme and solved by the cross particle swarm optimization and Floyd algorithm. The outcome of its application on the New England 10-unit 39-bus power system indicates that units’ restoration sequences obtained fully consider possible spare paths for restoration as well as minimization of outage loss. Therefore, the method proposed can more effectively cope with the potential failure during switching in lines. This work is supported by National Natural Science Foundation of China (No. 51277076). |
