With the rapid deployment of the advanced metering infrastructure (AMI) and distribution automation (DA), self-healing has become a key factor to enhance the resilience of distribution networks. Following a permanent fault occurrence, the distribution network operator (DNO) implements the self-healing scheme to locate and isolate the fault and to restore power supply to out-of-service portions. As an essential component of self-healing, service restoration has attracted considerable attention. This paper mainly reviews the service restoration approaches of distribution networks, which requires communication systems. The service restoration approaches can be classified as centralized, distributed, and hierarchical approaches according to the communication architecture. In these approaches, different techniques are used to obtain service restoration solutions, including heuristic rules, expert systems, metaheuristic algorithms, graph theory, mathematical programming, and multi-agent systems. Moreover, future research areas of service restoration for distribution networks are discussed.

配电网服务恢复审查

随着高级计量基础架构（AMI）和配电自动化（DA）的快速部署，自我修复已成为增强配电网络弹性的关键因素。在永久性故障发生后，配电网络运营商（DNO）实施自我修复方案，以定位和隔离故障，并为停运的部分恢复供电。作为自我修复的重要组成部分，服务恢复已引起广泛关注。本文主要回顾了需要通信系统的配电网服务恢复方法。根据通信体系结构，服务恢复方法可以分为集中式，分布式和分层方法。在这些方法中，使用不同的技术来获得服务恢复解决方案，包括启发式规则，专家系统，元启发式算法，图论，数学编程和多智能体系统。此外，讨论了配电网服务恢复的未来研究领域。
