Abstract：So far, few studies have been taken on power system damping control based on wide area measurement system with multiple time delay considered. Besides, robust control theory, as the main control solution of multiple time delay systems, is complicated in searching ideal parameters. In the light of this, a novel design strategy for wide area power system damping control with multiple time delay considered is proposed, and thus the parameters can be solved directly in a convenient and simple way. Lyapunov-Krasovskii theory is used to deduce the multiple time delay system stability criterion. Instead of the complicated iterative process by using intelligent algorithm, control parameters can be easily achieved by transforming control stabilization into linear matrix inequalities (LMI). The results of time domain simulation in 2-area 4-machine system indicate that the proposed control scheme can suppress the inter-area low frequency oscillation and improve power system stability.
