Abstract: 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.

Quasi oppositional harmony search algorithm based controller tuning for load frequency control of multi-source multi-area power system
TL;DR: In this paper, a load frequency control (LFC) study of single-area and interconnected two-area power system having diversified power sources was conducted and the optimal gains of the classical controllers (i.e., integral controller, proportional-integral controller and PID controller) were obtained by using a novel music-inspired metaheuristic harmony search algorithm (HSA) which incorporates quasi opposition based learning technique for memory initialization and also for generation jumping.
