This issue is dedicated to the topic of microgrid protection in the electric power industry. The importance of microgrids is reflected in their ability to enhance the resilience of critical facilities against high-impact events, such as those caused by extreme weather. These days, microgrids often employ multiple distributed energy resources (DERs) from renewable energy sources, most commonly solar in combination with storage. The protection system is a critical component of power system operation and responsible for identifying faults in the system or microgrid and isolating them before additional equipment is damaged. Microgrids are often connected to electric power distribution networks and operated interactively with distribution utilities, making microgrid protection and protection coordination with the main grid increasingly complex. Another layer of protection complexity is added if a microgrid is deployed on a secondary distribution network.

微电网保护：研发应对挑战[在我看来]

本期专门讨论电力行业中的微电网保护。微电网的重要性体现在它们增强关键设施对高冲击事件（例如由极端天气引起的事件）的弹性的能力。如今，微电网经常使用可再生能源中的多种分布式能源（DER），最常见的是太阳能与储能相结合。保护系统是电力系统运行的重要组成部分，负责识别系统或微电网中的故障，并在损坏其他设备之前将其隔离。微电网通常连接到配电网络，并与配电设施进行交互操作，这使得微电网保护和与主电网的保护协调变得越来越复杂。
