In this paper, a novel optimization algorithm based on uniform distribution of control variables and two-stage initialization processes in conventional PSO has been proposed to solve OPF problem. The objectives such as conventional quadratic, non convex costs and multi-fuel quadratic, non-convex costs are optimized while satisfying equality, inequality and practical constraints. The effect of multi-fuel on economic load dispatch has been presented with respective validations. The effect of practical constraints such as ramp-rate and POZ limits has been analyzed on the defined objectives.
