The fact of that the critical boundary of practical dynamic security region (PDSR) in real power systems can be described as one or a few hyper planes in injection space provides an effective tool for optimizing security control.

• 实际电力系统的实用动态安全域(practical dynamic security region,PDSR)的临界边界可表示为节点注入空间的一个或几个超平面,这为最优安全控制提供了有效的解析工具。
