A novel quasi-oppositional harmony search algorithm for automatic generation control of power system

摘要: For single-area NRTWD (a) comparative frequency deviation and (b) QOHS-based convergence profile of FOD. AGC study single- multi-area power systems by using a novel QOHS algorithm.Effects GRC in the studied three- five-area system model.Incorporation PID controller three-area systems.Investigation IDD performance system.Comparative analysis algorithm over other methods. This paper presents significances quasi-oppositional harmony search (HS) (QOHS) context automatic generation control (AGC) system. The proposed is framed utilizing concept pre-available basic HS algorithm. Also, houses both characters two guesses i.e. opposite-point its mirror point (quasi-opposite point) to converge rapidly toward optimal solution(s). is, individually, applied single-, interconnected test (considering suitable cases) for survival domain. are supplemented with proportional-integral-derivative (PID) installed each area. In second phase investigation, based integral-double derivative (IDD) also examined mechanism Initially, integral square error objective function minimized and, further, indices (such as time absolute error) calculated offered PID/IDD controller. To add some degree non-linearities, appropriate rate constraint (GRC) considered systems. simulated results, obtained algorithm, compared those optimization algorithms reported recent state-of-the-art literature. extensive presented this paper, reveal that may be, effectively, imposed boost having various degrees complexities (like model uncertainties) non-linearities GRC).
