Observer based sliding mode load frequency control for power systems with time delay

Abstract

The main objective of this thesis is to study and design load frequency control (LFC) newlinefor an interconnected multi area power system via sliding mode. Voltage and frequency of an newlineelectric power system are the two main parameters which require continuous monitoring and newlinecontrol. While voltage mainly depends on the reactive power; frequency depends on the newlineamount of mechanical power being generated and electrical power being consumed. Any newlinemismatch between the total generation and the total load demand leads to newlineacceleration/deacceleration of synchronous generators which in turn leads to change in newlinefrequency. Off-normal frequency can directly impact power system operation and reliability. newlineTherefore, frequency control is an important aspect of power system stability. newline
