Abstract: Nowadays power demand is increasing continuously and the biggest challenge is to provide good quality of power to the consumer under changing load conditions. For satisfactory operation, the frequency of power system should be kept near constant value. Continuous change in frequency by variation of load is a big challenge for generating unit to compensate it as quickly as possible. Many techniques have been proposed to obtained constant value of frequency and to overcome any deviations. The load-frequency control (LFC) is used to restore the balance between load and generation by means of speed control. The main goal of LFC is to minimize the transient deviations and steady state error to zero in advance. PID is a conventional controller that can be used for LFC to get faster and better results. If conventional Controller and power system stabilizer (PSS) are used together then more effective result can be achieved rather than their individual use for LFC. This paper presents a comparison of Multi-area LFC with and without conventional controller and conventional controller in the presence of power system stabilizer (PSS) using MATLAB/SIMULINK software package. Reduction in settling time, overshoot and frequency deviation was successfully achieved by Using PID controlled Power system Stabilizer (PSS).
