Abstract
Supply of energy with minimum production cost as view of consumer's payment is the most important challenge in recent researches. In other words, power supply during a day (24h) in the least costs, while satisfy the power system constraints is main aim of this paper. Since the dynamic economic dispatch (DED) had inherent nonlinearity therefore it makes a quite complexity inherent for the mathematical methods to solve it as view of computational burden. In this regard, we models dynamic economic load dispatch during a day with available constrains such as valve point effect, power system bound, ramp-rate constraints and etc and propose a new Modified Harmony Search Algorithm (MHSA) to solve it. In the proposed algorithm employ Chaos theory and local/global operators to improve search ability of original harmony search algorithm. At last, the proposed method assesses on available standard test systems compare to other existing methods. The results of the proposed method show acceptable performance in solving of nonlinear problem such as dynamic economic dispatch (DED). Also, the obtained results of the improved harmony search algorithm from test function show acceptable improvement in local search and global parts.
