中文摘要:
      故障恢复是未来智能配电系统实现自愈的关键环节,对满足用户供电需求和减少停电损失有重要作用。针对含分布式电源的主动配电网,提出了考虑主动管理措施的故障恢复方法。考虑分布式电源出力调节和电容器组无功补偿约束,首先,构建了主动配电网孤岛划分模型,利用深度优先搜索结合广度优先搜索的算法进行孤岛的划分。然后,建立了主动配电网故障重构模型,采用二阶锥松弛技术将其转化为混合整数二阶锥规划模型进行快速求解。最后,在改进的IEEE 33节点主动配电网算例上进行了仿真计算,算例结果验证了所述模型和方法的合理性和有效性。
英文摘要:
      Fault recovery is the key link to realize self-healing of intelligent distribution system in the future. It plays an important role in meeting the demand of power supply and reducing the loss of outage. For active distribution network with distributed generations, a fault recovery method considering active management measures is proposed. Considering the distributed power output regulation and the capacitor group reactive power compensation constraint, firstly, the active distribution network islanding model is constructed, and the depth-first search combined with the breadth-first search algorithm is used to divide the islands. Then, the active distribution network fault reconfiguration model is established, which is transformed into a mixed integer second-order cone programming model for fast solution by second-order cone relaxation technique. Finally, the improved IEEE 33-bus active distribution network is simulated, and the results show that the proposed model and method are reasonable and effective.
