ABSTRACT
Proportional-Integral-Derivative (PID) controller based Load Frequency Control (LFC) proposed here for controlling the frequency deviation which is a one of major technical issue of a two area interconnected power system. In order to improvise the performance of supplying power of a power system, error function is minimized. The objective function taken into consideration over here is Integral of Square of Error (ISE). To optimize the gain values of controller, the Particle Swarm Optimization (PSO) algorithm is used. Tuning of controllers is done in order to get the gain values or controller parameters such that the desired frequency and power interchange with adjoining systems are maintained within specific value. Controllers must possess the property of being sensitive against changes in frequency and load. Tuning of controllers based on PSO algorithm is justified by making a comparison with Conventional Ziegler–Nichols tuning method.
