  author={Kallol Das and Priyanath Das and Sharmistha Sharma},
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…
