Load frequency control is one of the most important issues in power systems. When the load is changed abruptly, the frequency of the system disrupts. To damp these deviations, the system controllers should be well tuned. In this paper, two types (thermal-thermal and thermal-hydro) of two-area multi-unit interconnected system are considered. To damp the system oscillations, Automatic Generation Control (AGC), Superconducting Magnetic Energy Storage (SMES) and Capacitive Energy Storage (CES) have been used. PSO algorithm has been applied to design the AGC and the controllers of SMES and CES. The system has been simulated for three cases; system with incorporation of just AGC in two areas, system with inclusion of AGC and CES and finally system with contribution of AGC and SMES in two areas. Simulation results show that contribution of AGC and SMES is superior to other configurations.
