Economic Load Dispatch Using Improved Harmony Search
نویسندگان
چکیده
This paper presents the use of the improved harmony search method for solving economic load dispatch problems. The harmony search method mimics a jazz improvisation process by musicians in order to seek a fantastic state of harmony. To assess the searching performance of the proposed method, a six-unit thermal generating system acquired from the standard IEEE 30-bus test system was challenged. Satisfactory results obtained from the proposed method were compared to those obtained by genetic algorithms, evolutionary programming, adaptive tabu search and particle swarm. Also, effects of valve-point loading units were included and discussed. Key-Words: Economic dispatch, genetic algorithms, evolutionary programming, adaptive tabu search, particle swarm optimization

متن کاملIntelligent Tuned Harmony Search for Solving Economic Dispatch Problem with Valve-point Effects and Prohibited Operating Zones
Economic dispatch with valve point effect and Prohibited Operating Zones (POZs) is a non-convex and discontinuous optimization problem. Harmony Search (HS) is one of the recently presented meta-heuristic algorithms for solving optimization problems, which has different variants. The performances of these variants are severely affected by selection of different parameters of the algorithm. Intel...
