中文摘要	Power system splitting (also called as system islanding) is to split the interconnected power grid into several islands when the system is subject to severe disturbances and system integrity can not be hold, so that the continuity of power service on the islands can be sustained. Recent interests have been concentrated on how to find out splitting strategies that satisfy certain constraints in an efficient way. But methods based on graph-model always collapse because computation complexity explodes too severely with the increase of the scale of power systems. Instead of taking all branches as candidates, this paper proposes a weak-connection-based method to form a much smaller candidate strategy space before any searching. Thereafter, an OBDD (ordered binary decision diagram)-based method is applied to search feasible strategies within the candidate subspace. Tests on IEEE-68 systems show that the proposed method works well in large-scale power system.
