Abstract :
A fuzzy gain scheduling PI controller based on particle swarm optimization (PSO) is proposed for multi-area interconnected automatic generation control (AGC) system after deregulation in this paper. Approved PSO algorithm has been used for optimizing parameters of fuzzy logic controller to maintain global optimum. This control scheme adopts new area control error (ACE) which takes time error and inadvertent interchange accumulation into account. Distribution company (DISCO) participation matrix (DPM) is introduced to simulate the bilateral contracts. The proposed approach achieves better dynamic performance compared with conventional proportional and integral (PI) controller and fuzzy logic controller (FLC) in four-area reheat thermal and hydro AGC system.
