Optimal scheduling of power system using harmony search algorithm

Nonlinear optimal control problem is transformed into a multi-objective mathematical optimization problem. Harmony search (HS) algorithm is one of the new heuristics. In HS optimization algorithm is introduced for the first time in solving the short-term cascade hydroelectric power generation system plan. Canal head power house of the potential energy on the release of the best estimate of the situation presented to show the feasibility and efficiency of the method compared with conventional methods, optimization algorithms HS search time becomes short, the result is close to the ideal solution, at the same time.
