A comprehensive review on swarm intelligence methods applied to practical economic load dispatch problem

Abstract

Background: In the modern era, a power production industry is to be extremely vibrant and reliable in the electricity market aspect with the introduction of restructuring process. Methods: In the recent past, a power plant with the combination of generating units should pace under economic condition. The optimal economic dispatch is highly essential as deplete of fossil fuel with increase in electric demand. The main objective of Economic Load Dispatch (ELD) problem in the power system is to minimize the generating cost. Results: Economic dispatch scheduled the electric power as per the load demand satisfying all the practical and operational constraints. This paper presents and explores the comprehensive review of swarm intelligence methods applied to solve the economic dispatch problem. Swarm intelligence techniques as a part of nature-inspired algorithm, inspired from the behavior of swarm for the application it in real complex problem. Conclusion: Many swarm intelligence methods were applied to solve the economic dispatch problem effectively with the conventional methods and modifications.
