“…So far, an enormous variety of artificial intelligence (AI) algorithms, including genetic algorithm (GA) [23], quantum genetic algorithm (QGA) [24], artificial bee colony (ABC) [25], particle swarm optimization (PSO) [26] and bacteria foraging optimization (BFO) [27,28] have been successfully applied for an optimal power system operation due to their elegant merits of global convergence, model free feature, and applicability to discrete nonlinear problems. In particular, an optimization task can be tackled by variables, objective functions and the number of unsatisfied constraints.…”
