Inverter-based resources are proliferating in distribution systems across the globe, along with battery energy storage systems. This in part is attributed to a descending trend observed in their costs. These inverter-based resources, however, create new problems for electrical utilities planners and engineers. One such issue is how to measure, test, and manage load rejection overvoltage. This phenomenon takes place upon sudden islanding of a power system area such that it becomes supported by grid-following inverter-based resources only. This letter presents background, practical methods to test the behavior, as well as two case studies of utility-scale generation and energy storage connected to a distribution feeder.

配电连接 IBR 的负载抑制过压


基于逆变器的资源以及电池储能系统正在全球各地的配电系统中激增。这部分归因于其成本呈下降趋势。然而，这些基于逆变器的资源给电力设施规划人员和工程师带来了新的问题。其中一个问题是如何测量、测试和管理甩负载过压。这种现象发生在电力系统区域突然孤岛以致仅由并网逆变器资源支持时。这封信介绍了背景、测试行为的实用方法，以及连接到配电馈线的公用事业规模发电和储能的两个案例研究。
