电力系统在接近其稳定极限的情况下运行，这增加了连锁停电导致大面积停电的可能性。为了缓解这些现象，有意控制孤岛（ICI）已被建议作为一个有效的纠正策略，分裂成可持续的子系统（岛屿）的系统。有两个主要方面与ICI相关：i）在哪里岛，和ii）何时岛？这项工作侧重于后者，并提出了一种基于风险的方法，以实时方式进行比较（即，足够快）没有孤岛和有孤岛的系统的总体风险（即，当ICI方案被激活时），以便定义用于系统分裂的合适时间。IEEE 9节点系统的仿真结果表明，在确定一个合适的时间创建的岛屿，这反过来又对应于没有和孤岛的系统的风险之间的交叉点的方法的有效性。
Power systems are operated close to their stability limits and this increases the probability of cascading outages leading to large-area blackouts. To mitigate these phenomena, intentional controlled islanding (ICI) has been suggested as an effective corrective strategy that splits the system into sustainable subsystems (islands). There are two primary aspects associated with ICI: i) where to island, and ii) when to island? This work focuses on the latter and proposes a risk-based methodology that compares in a real-time fashion (i.e., quickly enough) the overall risk of the system without and with islanding (i.e., when an ICI scheme is activated) in order to define a suitable time for system splitting. Simulation results on the IEEE 9-bus system demonstrate the effectiveness of the methodology in determining a suitable time for the creation of islands, which in turn corresponds to the crossing point between the risks of the system without and with islanding.
