Abstract

The enhancement of power system transient stability is investigated in this paper. After the idea of enhancing transient stability by changing network configuration is clarified, two screening indices used to select the candidate operations that can enhance transient stability are defined. At last, a heuristic strategy for enhancing transient stability is proposed. Because the screening indices are based on Z-matrix. the proposed method is both simple and practical. The results of two test systems support the proposed idea, and the effectiveness of the proposed heuristic strategy is verified by the computed results of a realistic system.
