摘要/Abstract

摘要： 现有配电网自愈方案无法达到在线要求。为此，提出一种基于混合整数线性规划的配电网在线自愈方案。首先，构建一种集中式的5G通信网络架构，解决在线自愈方案实现的通信阻碍；其次，分别构建一种基于混合整数线性规划的故障定位模型和供电恢复模型，有效解决配电网规模较大时自愈计算时间过长问题；最后，将故障定位和供电恢复整合成一个自愈模型，故障发生后只需进行一次自愈运算，就可以同时发出故障隔离和供电恢复命令。配电网算例表明：基于混合整数线性规划的故障定位模型和供电恢复模型求解速度明显提高，在所提5G通信架构下，所提配电网自愈方案能够满足在线自愈要求。

Abstract: The existing distribution network self-healing schemes cannot meet the online requirements. In this regard, an online distribution network self-healing scheme based on mixed integer linear programming is proposed. First, we build a centralized 5G communication network architecture to solve the communication obstacles implemented by the self-healing solution. Secondly, a fault location model and a power supply recovery model based on mixed integer linear programming are respectively constructed to effectively solve the problem that the self-healing calculation time is too long when the scale of the distribution network is large. Finally, the fault location and power supply restoration are integrated into a self-healing model. After a fault occurs, only one self-healing operation is required to issue fault isolation and power supply restoration commands at the same time. The distribution network example shows that the solution speed of the fault location model and power supply recovery model based on mixed integer linear programming is significantly improved. Under the proposed 5G communication architecture, the proposed distribution network self-healing scheme can meet the online self-healing requirements.

Key words: distribution network, online self-healing, mixed integer linear programming, fault location
