Improved harmony search algorithm for economic emission dispatch

Abstract

The economic emission dispatch (EED) assumes a lot of significance to meet the clean energy requirements of the society and simultaneously minimizes the cost of generation. The harmony search algorithm (HSA), mimicking the improvisation process of music players, is a music inspired heuristic algorithm; and searches for optimal solution through the memory consideration and pitch adjustment. This paper presents an Improved HSA (IHSA) based strategy for obtaining the robust solution of EED problem. The feasibility of the proposed approach is evaluated through three test systems and the results are presented to highlight its suitability for practical applications.
