ABSTRACT: Load Frequency Control (LFC) is one of power systems
important requirements which maintain the zero steady-state errors in the
frequency changing and restoring the natural frequency to its normal position.
Many problems are subject to LFC such as suddenly large load or suddenly
disconnecting generating unit by the protection device. In this paper,
multi-area Frequency Control by using the combination of PSO and fuzzy logic
control (FLC) technique. PSO optimization method is used to tuning the fuzzy
controller input and output gains. Four of an interconnected electrical power
system used as a testing the effectiveness of the proposed method compared to a
conventional PI controller and scaled-fuzzy controller. The simulation result
has been shown that the controller can generate the best dynamic response in
multi-load conditions.
