微电网已被提出作为一个有吸引力的解决方案，利用分布式能源（DER）提供的好处。然而，尽管微电网具有优势，但它也给电网带来了新的挑战。特别是，它们可能影响配电系统中的传统保护做法。这主要是由于DER的存在，不同的微电网运行模式以及各种网络配置。本文将提供一个最新的概述和分析的保护方案，已设计和/或实施的主要北美微电网项目。本文还简要概述了微电网保护问题和潜在的解决方案，以帮助设计人员确定实际微电网的保护要求。
Microgrids have been proposed as an attractive solution to harness the benefits offered by distributed energy resources (DERs). However, despite their advantages, microgrids introduce new challenges to electric grids. In particular, they can impact conventional protection practices in distribution systems. This is mainly due to the presence of DERs, different microgrid operational modes, as well as various network configurations. This paper will provide an up-to-date overview and analysis of the protection schemes that have been designed and/or implemented in major North American microgrid projects. A brief overview of the microgrid protection issues and potential solutions are also presented in the paper to help designers with defining protection requirements for practical microgrids.
