PSO approach for ELD problem: A review

Abstract

The increase in real power demand on the distribution side of power system affects the cost of power generation. The main objective is to schedule the total demand among all the units in a thermal plant with minimum fuel cost by applying an intelligent technique. There are many conventional and intelligent techniques which are in practice for the economic dispatch of thermal units. In recent days intelligent techniques are playing key role in many applications because of its simple application. The results obtained by applying Particle Swarm Optimization (PSO) to 3 and 6 unit test cases are compared to other techniques. PSO is one of the intelligent techniques and is simple in application when compared to other existing intelligent techniques.
