Abstract: This paper presents a multi-objective optimisation technique for the design of a static synchronous series compensator (SSSC)-based controller. The design objective is to improve the transient performance of a power system subjected to a severe disturbance by minimising the power angle, terminal voltage and power flow time trajectory deviations with respect to a post-contingency equilibrium point for a power system installed with a SSSC. A genetic algorithm (GA)-based solution technique is applied to generate a Pareto set of global optimal solutions to the given multi-objective optimisation problem in power systems. The optimal gain and time constant values for the proposed SSSC-based controller are determined in a generator-infinite-bus test system. Simulation results show the effectiveness and robustness of the proposed approach in improving transient performance of the example power system.

Keywords: computational algorithms; multi-objective optimisation; Pareto solution set; power system stability; static synchronous series compensator; SSSC; controller design; power systems; genetic algorithms; simulation.
