Enriched Biogeography-Based Optimization Algorithm to Solve Economic Power Dispatch Problem

Abstract

This article offers an enriched biogeography-based optimization (EBBO) technique to crack the economic power dispatch (EPD) problem of coal-fired generating units. The considered EPD involves the complex limitations including valve point loading effects, transmission line losses, and ramp rate limits. The geographical smattering of biological species is the vital scope of this algorithm. The proposed EBBO describes the arousal, enhanced migration of species from one environment to another. The algorithm has two main steps specifically, migration and mutation. These steps are involved in searching the global optimum solution. The EBBO’s efficiency has been verified on 13 and 40 generating test systems. The proposed technique produces superior results when compared with the conventional biogeography-based optimization (BBO) and other prevailing techniques. Also, it gives the quality and promising results for solving the EPD problems. Further, it can be applied for practical power system.
