The articles in this special section focus on the challenges faced by power grids worldwide. Global electric power systems are facing unprecedented challenges worldwide. Extreme events such as hurricanes, wildfires, and earthquakes have fundamentally changed the way the power grid is designed and operated. Power system planning and operation ought to go above and beyond the classical reliability indices that have governed industry practices for many decades. The fact that extreme events are of high impact and low frequency (HILF) renders traditional reliability- oriented system-enhancement measures insufficient and ineffective. Rather than focusing on routine power system component failures and outages, resilience specifically refers to the ability of a system to anticipate, absorb, react to, and recover from a rare, widespread, quickly changing, and extreme event scenario that may cause substantial and enduring damage to our society.

电力系统的弹性：未来电网的黄金法则[访客社论]

本节中的文章重点介绍了全球电网所面临的挑战。全球电力系统正面临全球范围内前所未有的挑战。飓风，野火和地震等极端事件从根本上改变了电网的设计和运行方式。电力系统的规划和运行应该超越控制行业实践数十年的经典可靠性指标。极端事件具有高影响力和低频（HILF）的事实使传统的面向可靠性的系统增强措施不足且无效。弹性不是在关注常规电力系统组件的故障和停机，而是专门指系统预测，吸收，反应并从罕见，广泛，快速变化的状态中恢复的能力，
