Abstract

This paper presents the effects of load parameters and their variations on power system frequency and tie-line power. In this study the authors have selected two area thermal power system with Integral (I) and PSO-PID (Practice Swarn Optimization-Proportional-Integral Derivative) controllers. From the mathematical modelling of power system, frequency is a function of power system parameters and small changes in these parameters lead to small deviations in the system frequency and tie-line power. In case of extreme ends of parameters, even for small changes in load power there will be a chance of instability in overall power system. This paper deals with stable case for different parameter variations. Simulations are carried out in MATLAB/SIMULINK software.
