Abstract: The ability of a Redox Flow Battery (RFB) is analysed in the present paper to minimise the tie-line power and frequency deviations of the five-area thermal power system. Initially, a power system network with five areas and a non-linearity of Generation Rate Constraint (GRC) is designed in MATLAB/SIMULINK environment. After that, the values of Proportional Derivative-Proportional Integral Derivative (PD-PID) controller are evaluated for the proposed system by using Search Group Algorithm (SGA). The best control parameters of PD-PID controller are selected by having objective function as Integral Time Multiplied Absolute Error (ITAE). Finally, the RFB is installed in area-1, area-2, area-3, area-4 and area-5 for dynamic response enhancement. Results of simulation show that, better transient response characteristics can be obtained by using PD-PID controller along with RFB in area-1. Further, the system is also tested after inclusion of two RFBs in the control areas. Finally, the robust analysis is also performed to show the capability of the proposed method.

Keywords: dynamic response; generation rate constraint; PD-PID controller; redox flow battery; search group algorithm; transient response.
