In an electric power systems, the transmission system become increasingly subject several constraints and difficulties to operate. In this paper, a Multi-Objective Evolutionary Algorithm (MOEA) to solve optimal reactive power (VAR) dispatch problem with Flexible AC Transmission System (FACTS) devices is presented, because their rapid response and enhanced flexibility to change the network parameters. This non linear Multi Objective Problem (MOP) consists to minimize simultaneously real power loss in transmission lines and voltage deviation at load buses. Static Synchronous Series Compensator (SSSC) is considered and described by mathematical models. Genetic algorithm is used to optimize the various functions in a power system with introduction of SSSC devices. The simulation was performed on the 6-bus system and implemented using MATLAB package.
