满足自适应解列的快速性要求.

Abstract

Self-adaptive system islanding refers to the separation of an interconnected power system into electrically isolated islands automatically based on the identification of unstable mode. A fast searching algorithm for self-adaptive power system islanding

called multilevel reduced graph partitioning algorithm(MLRGPA)

is presented to make the generation load imbalance in each island as small as possible. A reasonable islanding strategy of power system is proposed

and a C++ program is developed to realize the algorithm. The islanding program is verified with the simulations for a practical 212-bus power system. It takes only 20 ms to get a reasonable islanding strategy on an ordinary PC to satisfy the rate requirement of self-adaptive system islanding.
