Modified Particle Swarm Optimization Technique for Dynamic Economic Dispatch Including Valve Point Effect

Abstract

The problem of Economic Dispatching (ED) is crucial to the functioning of the power grid because it provides the generators with an optimum schedule such that the overall generation running costs are minimized while fulfilling the generator and system constraints. Conventional ED takes little account of the valve’s point load on cost curve, the probability of rising and reducing fuel. The above problems cannot be overlooked, because they are a more practical solution to ED’s problem. The ED problem is called dynamic economic dispatch (DED), taking into account the ramp limits and valve point effects. The purpose of this work is to solve the problem of a ten generators DED system using modified particle swarm optimization (MPSO) approach. The solution achieved by MPSO provides the best possible solution compared to PSO, and the outcomes are discussed properly.KeywordsDynamic economic dispatchRamp rate limitsValve point effectModified particle swarm optimization (MPSO)
