Static synchronous compensator (STATCOM) is a device in the Flexible AC Transmission System (FACTS) that can be used to keep a constant voltage profile at the buses in the power system and controls the power flow in a transmission line's specified bus. This paper shows how to utilize the STATCOM to calculate steady-state power flow in a power system in a simple way. The proposed algorithm is based on the Jumping Frog Practical Swarm Optimization (JFPSO) technique to determine the best location of the STATCOM in the power system as follow buses 11, 12, 13, and 14 of IEEE 14-bus and 6, 11, 24, 27, and 30 of IEEE 30-bus systems. The proposed algorithm is compared to the IEEE 14-bus and IEEE 30-bus systems in Matlab/Simulink. The simulation results demonstrate that the proposed algorithm is effective in terms of accuracy and improvement the voltage of buses with constrain.
