Abstract :

For maintaining the load frequency control of power systems, as supplementary controllers, PID controller with redox flow battery are employed in the current paper to study the system’s response. The system was simulated and the output responses of frequency deviations in area 1 and area 2 for 1% step–load disturbance have been obtained. The frequency deviations for two area interconnected thermal power systems are compared with PID controller with Redox Flow Batteries (RFB) using MATLAB simulations. The results reveal that the PID controller with Redox flow battery improves the performance drastically. The mean square error is also calculated. In respect of PID controller with Redox flow battery in area1 is 7.2631E–09 and in area2, the error is 1.36E–08.
