Application of Particle Swarm Optimization for Economic Load Dispatch and Loss Reduction

Authors: S. Auchariyamet, N. Phanthuna, J. Jaturacherdchaiskul, S. Lerdvanittip


This paper proposes a particle swarm optimization (PSO) technique to solve the economic load dispatch (ELD) problems. For the ELD problem in this work, the objective function is to minimize the total fuel cost of all generator units for a given daily load pattern while the main constraints are power balance and generation output of each units. Case study in the test system of 40-generation units with 6 load patterns is presented to demonstrate the performance of PSO in solving the ELD problem. It can be seen that the optimal solution given by PSO provides the minimum total cost of generation while satisfying all the constraints and benefiting greatly from saving in power loss reduction.

Keywords: Particle Swarm Optimization, economic load dispatch, loss reduction
