The papers in this special section focus on resilience-oriented protection control and monitoring systems for power grids. Existing protection and control systems have been developed based on the properties and requirements of the legacy power system. However, the severity, frequency, and diversity of large-scale disturbances that can disrupt normal operation of power grids have increased. For instance, the number of major climate disasters has risen substantially, and the grid has been exposed to cyber-attacks due to the expansion of a host of different communication-dependent features/elements. In the meantime, various emerging components of modern grids can potentially be a major asset to improve the grid resilience. For example, islanded microgrids can ensure the continuity of service during major disruptions in the transmission system. Wide-area measurement systems also can provide predictive data in the event of large-scale disturbances, thus expediting mitigative measures. These recent developments have led to renewed and intensified efforts to meet the demands for higher levels of grid resilience. Protection, monitoring, and control systems will play a major role in these efforts by either preventing largescale disruptions or enabling the grid to cope with their consequences.

以弹性为导向的电网保护、控制和监测系统的客座社论特刊

本专题中的论文重点介绍电网的面向弹性的保护控制和监测系统。现有的保护和控制系统是根据传统电力系统的特性和要求开发的。然而，可能扰乱电网正常运行的大规模干扰的严重性、频率和多样性有所增加。例如，重大气候灾害的数量大幅增加，并且由于大量不同的依赖于通信的特征/元素的扩展，电网已经暴露在网络攻击中。与此同时，现代电网的各种新兴组件可能成为提高电网弹性的重要资产。例如，孤岛微电网可以确保在输电系统发生重大中断期间服务的连续性。广域测量系统还可以在发生大规模干扰时提供预测数据，从而加快缓解措施。这些最近的发展导致重新和加强努力，以满足对更高水平的电网弹性的需求。保护、监测和控制系统将通过防止大规模中断或使电网能够应对其后果而在这些努力中发挥重要作用。
