“…Hybrid methods considered as an alternative and robust solution to combine different methods. In the recent literature various hybrid methods have been proposed and applied with success for solving many complex and combined problems related to power system planning, operation and control, some of these techniques are, Evolving ant direction differential evolution [29], A modified teaching-learning based optimization [30], hybrid differential evolution (DE) with particle swarm optimization (PSO) [31], hybrid fuzzy particle swarm optimization and Nedler-Mead algorithm (HFPSO-NM) [32], chaotic improved PSO [33], hybrid imperialist competitive-sequential quadratic programming (HIC-SQP) algorithm [34], A modified shuffle frog leaping algorithm [35], new modified and hybrid modified imperialist competitive algorithms [36], adaptive biogeography based predator-prey optimization technique [37], self-evolving brain-storming inclusive teaching-learning-based algorithm [38], A hybrid GA-PS-SQP [39] and hierarchical adaptive PSO [40]. As well described in the literature review, the structure of these methods is based on how adjusting dynamically their parameters and on combination between various methods to exploit efficiently the best performances of each method to achieve the global solution at a reduced time.…”
