TIDF + Second derivative Order controller for Load Frequency Control of a two-area thermal power system by DE method

In this study, a special TIDFD2 controller that is positioned in both the first area and the second area is advised for load frequency management of two-area nonreheat thermal unit power systems. In the below system model controller parameter are tuned by the help of differential evolution algorithm. An effort has been made to prove that the TIDFD2 controller is showing better result as compared to other controller which is recently being published like Firefly Algorithm optimized PID controllers and differential evolution algorithm optimized TIDF controllers in the same thermal power system. From Simulink response it is found that settling times, overshoots of tie-line power deviation and frequency are better as compared to recently published work. Hence TIDFD2 controller is having better response following a disturbance.
