In this paper, Load Frequency Control (LFC) of isolated single area and two-area re-heat inter-connected thermal power system has been carried out by the classical controllers i.e. I, PI and PID; and implemented on the system at 1% step load perturbation under nominal loading conditions. The system responses have been simulated in MATLAB R2010a. Responses of deviation in frequencies, deviation in tie-line power and choosing the optimum controller (i.e. better among I, PI & PID controllers) gain values (i.e. ) to have better dynamic responses of the system have been plotted, keeping in view the characteristics such as rise time, settling time, oscillations & peak overshoot. Thus, on the basis of these responses, the dynamic performance of the system has been studied. Effect of variation in regulation parameter (R) and also step load perturbations is simulated for different values. The simulation results indicate that better control performance in terms of overshoot and settling time can be achieved by choosing PID among the other considered classical controllers.
