Solving Optimal Power Flow Problems Using Harmony Search Method
This paper presents optimal power flow solutions in which the system production cost is set as the objective. Harmony Search (HS) was selected as an efficient intelligent search method. The standard IEEE 6- bus and 30-bus test systems were used for evaluation. The satisfactory results obtained by the HS method were compared with those obtained by Quasi-Newton methods (BFGS) and Genetic Algorithms (GA). As a result, the HS method showed performances in finding optimal solutions for the optimal power flow problems.
