Abstract: The coordinated design of power system stabiliser (PSS) and a static synchronous compensator (STATCOM)-based controller for power system stability improvement is presented in this paper. The design problem is formulated as a parameter constrained, simulation-based, non-linear optimisation problem and bacteria foraging optimisation algorithm (BFOA) is employed to determine the optimal controller parameters. The performance of the proposed controllers is evaluated and compared with a conventional power system stabiliser (CPSS) in a single-machine infinite-bus power system subjected to various transient disturbances. The non-linear simulation results show that the proposed coordinately designed STATCOM-based controller and PSSs improve greatly the system damping and are robust to variation in operating conditions and fault clearing sequence. Finally, the coordinated design problem is extended to a four-machine two-area system and the results show that the inter-area and local modes of oscillations are well damped with the proposed BFOA-optimised controllers.
