Abstract
In this investigation, a new application of PID-P controller for developing the performance of LFC is presented. The PID-P controller is proposed to overcome the structure limitation of PID in controlling the integration process. At first, a two-area of non-reheat thermal system is considered to investigate the performance of the proposed controller. Further, the proposed controller is extended to a more realistic power system model including thermal with reheater, hydro, wind and diesel power generation units with physical constraints such as governor dead band (GDB), generation rate constraint (GRC) time delay and boiler dynamics. The parameters of the PID-P controller are optimized using linearized biogeography based optimization technique (LBBO), biogeography based optimization (BBO) and genetic algorithm (GA) with integral of time multiplied absolute error (ITAE) as a fitness function. The superiority of the proposed PID-P controller is examined by comparing its results with some recently published modern heuristic optimization approaches tuned PI, PID, 2-Degree of freedom PID (2-DOF-PID), fuzzy-PI, fuzzy PID, IDD, PIDD controllers for the same power systems. Moreover, the ability of the proposed controller to handle large variation in operating load conditions, time delay, participation factors and system parameters has been verified comprehensively
