摘要:

针对交直流混合配电网特殊的网架结构和电气特性，构建交直流混合配电网故障恢复模型。所提出的模型以故障恢复综合满意度指标为目标函数，并计及潮流约束、节点电压约束、支路传输约束和网络辐射状约束等约束。对所建立的模型设计两阶段优化求解流程，第一阶段采用二进制粒子群算法进行求解，第二阶段采用粒子群算法进行求解。最后通过一个算例表明，交直流混合配电网故障位置对故障恢复策略以及故障恢复综合满意度指标有着较大影响，同时所提出的模型适用于交直流混合配电网故障恢复问题。

Abstract:

According to the special grid structure and electrical characteristics of AC/DC hybrid distribution network, a fault recovery model of AC/DC hybrid distribution network is constructed. The proposed model takes the fault recovery comprehensive satisfaction index as the objective function, while considering the power flow constraint, the node voltage constraints, the branch transmission constraints, the network radiation constraint, and so on. A two-stage optimization process is designed to solve the established model. In the first stage, the binary particle swarm optimization is used to solve the problem, then the second stage optimization is solved by particle swarm optimization. Finally, an example shows that the fault location of AC/DC hybrid distribution network has a great influence on the fault recovery strategy and the fault recovery comprehensive satisfaction index, and it is applicable to the fault recovery of AC/DC hybrid distribution network. This work is supported by Science and Technology Project of the Headquarter of State Grid Corporation of China (No. kj2018-063).
