A Low Order System Frequency Response Model for Large Power System and Adaptive Load Shedding

Abstract

Now a days electrical system becomes very much large and Power demand will be increasing more and more. To satisfy the power demand nonconventional sources are incorporated in the field of electrical power generation and the system becomes Inter connected. Large power system disturbances sometimes causes interconnected system to become separated into some islands and it has either surplus of generation or load. If generation is more than it can be controlled by controlling the speed of speed governors connected with the generating station will result into change in frequency. This paper includes the derivation of simple low order system frequency response (SFR) model that can be used for estimating the frequency behaviour of the interconnected power system to sudden load disturbances. The SFR model is the simplify model to analyse system dynamics.
