Abstract: This paper presents a Multi-objective Genetic Algorithm (MGA) approach to generate Pareto solution set for coordinated design of a Power System Stabiliser (PSS) and a Flexible AC Transmission System (FACTS) controller. The design objective is minimisation of both angle and voltage time trajectory deviations with respect to a post-contingency equilibrium point for a power system installed with a PSS and a FACTS controller. The optimal controller parameters are coordinately determined in a generator-infinite-bus test system. Simulation results are presented to show the effectiveness of the proposed approach in damping the power system oscillations and improving the system voltage profile.

Keywords: MGA; multi-objective genetic algorithms; Pareto solution set; TCSC; thyristor controlled series compensator; PSS; power system stabiliser; power system stability; optimal control.
