Abstract :
In this paper, the Static Economic Dispatch (SELD) problem has been optimized by applied a novel approach named improved dynamic harmony search (IDHS) algorithm. The proposed method in this work uses a novel technique for generating a new solution, where the distance bandwidth (BW) is dynamically update to improve the exploration and exploitation characteristics of the original HS. The principle behind this idea is to use a large BW to search in the entire domain and dynamically adjust the BW towards the optimal solution. The IDHS algorithm is validate for a test system consisting of 13 thermal units with VPE. It is observed that IDHS has shown promising performance to solve the SELD problem with valve-point loading effects, the simulation results are compared with conventional HS and various other optimization algorithms published recently.
