Abstract:
This paper attempts to develop a linearized model of
load frequency control (LFC) for an interconnected reheat type
two-area thermal power system under deregulated environment.
A conventional Integral controller is optimized using ISE
optimization technique. A comparison between a conventional
optimized integral controller and a fuzzy logic based controller is
presented and the proposed fuzzy based controller is shown to
generate the improved dynamic response following a step load
change with combination of poolco and bilateral contracts in
deregulated environment. In addition, performance of
conventional integral controller and a fuzzy logic based
controller is also examined under various changes up to ±30% in
system parameters.
