Permutation Based Harmony Searching Optimization Technique in Economical Load Dispatch requirement

Different optimization techniques are available in various research publications, namely PSO, DE, HS, etc. All or many of these methods have been applied in different power system area like optimal placement of DG, optimal switching to get optimal load requirement etc. as well as power electronics applications and are found to be performing satisfactorily. But it has been observed that existing methods have some limitations related to convergence time, reaching towards optimal solution or global solution, or positional based solution and complexity of algorithm. So, researchers are developing new optimization techniques day by day with new innovations (value addition and value updating way in algorithms). In this paper, a new Permutation Based Harmony Searching Optimization (PBHSO) Technique has been proposed and applied in two different cases. Firstly it has been applied to a two variable function and then secondly applied to a six-unit power system network. The simulation and result are compared and it has been observed that over (multi-objective) [1], [2], [3] point of view the proposed PBHSO gives a better result than existing methods.
