Investigation and analysis of soft Computing based intelligent Controllers for load frequency Control in deregulated power system

Abstract

The modern power system is complex in structure with a large newlinenumber of interconnections The load on a power system varies based on newlineuncertain demands of consumers due to this generation and the demand newlinebecomes unequal which in turn causes frequency oscillations and tieline newlinepower deviations This will lead the power system into the unstable condition newlinehence it is always necessary to maintain the generation and the demand newlineequal This can be accomplished by regulating the power output of the newlinegenerators, and is known as Load Frequency Control LFC The main goals newlineof LFC are to restore the primary frequency regulation capacity and to hold newlinethe frequency at the scheduled values and to minimize the change in the newlineunscheduled tieline power flow between the neighboring control areas newlineSince the frequency is controlled by controlling the output of the generators, newlineLFC is also known as Automatic Generation Control newline newline
