| 摘要: |
| 通过支路数组元素的有效组合形成恢复方案，并利用负荷相对适应度和风险度指标引导恢复方案优化过程。通过合理投切可控负荷充分利用故障后剩余电源容量，在保障重要负荷供电的同时，尽可能恢复更多失电负荷。同时，将馈线间联络线和分布式电源在非故障失电区进行供电孤岛划分，并实现协调恢复。针对分布式电源和备用联络线在初始孤岛划分方案形成时存在的独立性和在优化过程中的关联性，引入包括信息层、执行层、设备层和协调层的多代理系统，进行并行计算、协调优化。采用69节点算例进行仿真，仿真结果验证了方法的正确性和有效性。 |

| Abstract: |
| The elements of branch array are effectively combined to form the power restoration scheme and the relative load fitness and risk degree are applied as index to guide its optimization procedure. For the full use of the post-fault remaining power capacity, the controlled loads are reasonably switched to guarantee the power supply for the critical loads while restore the de-energized loads as more as possible. Power-supply island partitioning is carried out for the healthy area to divide the tie-lines between feeders and the DGs(Distributed Generations) for realizing the coordinated restoration. Aiming at the independency of DGs and spare tie-lines during the preliminary island partitioning and their relevancy during the optimization process, a multiagent system including information layer, execution layer, equipment layer and coordination layer is adopted for the parallel computation and coordinated optimization. The feasibility and effectiveness of the proposed method are verified by the simulation for 69-bus test system. |
