A Robust Artificial Bee Colony-Based Load Frequency Control for Hydro-Thermal Interconnected Power System

The presented work examines load frequency control (LFC) to develop the dynamic behavior of power system under different disturbances that have occurred in multi-interconnected systems. An artificial bee colony (ABC) algorithm is proposed design an optimal proportional integral derivative (PID) controller simulating LFC installed a hybrid hydro-thermal interconnected system. approach incorporating ABC employed determine parameters during disturbance applied on one area. time absolute error (ITAE) and exchange violations considered as target be minimized. Moreover, (IAE) sum squared (SSE) are calculated. To prove how model effective, two-interconnected systems wide range operating cases, then compared designed via chef-based optimization (CBOA), seagull (SOA), sine cosine approach. Regarding 5% thermal plant, outperformed other approaches hence achieving best fitness value 1.80936, IAE 3.147938, SSE 0.1787486. On hand, hydro succeeded getting ITAE, IAE, with values 3.43291, 3.630509, 0.5233815, respectively. efficiency prevalence LFC-PID confirmed by achieved results.
