AUTOMATIC GENERATION CONTROL (LOAD FREQUENCY CONTROL) IN TWO AREA POWER SYSTEM FINAL YEAR PROJECT REPORT

Abstract

The main aim of this thesis is to reduce the damping an oscillation of frequency and it also deals with the automatic generation control (AGC) of two areas interconnected hydraulic power systems. The major problem arising from large scale electric power system interconnection is the low frequency oscillation of interconnected system. The primary object of the AGC is to balance the total system generation against system load and losses, so that the desired frequency and power interchange with neighboring systems are maintained in order to minimize the transient deviations and to provide zero steady state error in appropriate short time. For a complete system model we have to study the oscillation of AGC loop with PID CONTROLLERS. This model of AGC is tested on two-area power system. The result is shown in simulation; and will be reachable in dynamic and steady state responses. The simulation results of two areas are compared using MATLAB/SIMULINK software by using PID controllers and PID controllers can be tuned by using many methods. In all methods an initial guess is made for PID controller parameter settings. Then these parameter settings are improved by fine tuning of the controller.
