Economic Load Dispatch Problem Using Particle Swarm Optimization Technique: A Review

Economic Dispatch (ED) optimization problem is the most important issue which is to be taken into consideration in power systems. The problem of ED in power systems is to plan the power output for each devoted generator unit in such a way that the operating cost is minimized and simultaneously, matching load demand, power operating limits and maintaining stability. This problem becomes more complex in large scale power systems, as it is hard to find out optimal solution because it is nonlinear function and it contains number of local optimal. Various techniques are proposed by the researchers for ED. The main objective of ED techniques is to minimize the total cost of the emission while maintaining stability of the power systems. This paper presents a review on particle swam optimization (PSO) for solving economic load dispatch problem.
