Economic dispatch solution using efficient heuristic search approach

摘要

A new efficient hybrid differential evolution algorithm with harmony search (DE-HS) is proposed in this paper to solve the economic load dispatch (ELD) problem. The fresh individual generation mechanism of harmony search (HS) is utilized to enhance the local search capability of the original differential evolution (DE) method. The proposed hybrid algorithm is validated using the IEEE 30 bus test system and the practical Algerian 59 bus system. The results confirm the suitability of the proposed strategy to find accurate and feasible optimal solutions for ELD problems.
