Evolutionary programming techniques for economic load dispatch

Evolutionary programming techniques for economic load dispatch Evolutionary programming techniques for economic load dispatch Abstract: Evolutionary programming has emerged as a useful optimization tool for handling nonlinear programming problems. Various modifications to the basic method have been proposed with a view to enhance speed and robustness and these have been applied successfully on some benchmark mathematical problems. But few applications have been reported on real-world problems such as economic load dispatch (ELD). The performance of evolutionary programs on ELD problems is examined and…

Biogeography-Based Optimization for Different Economic Load Dispatch Problems

Biogeography-Based Optimization for Different Economic Load Dispatch Problems Biogeography-Based Optimization for Different Economic Load Dispatch Problems Abstract: This paper presents a biogeography-based optimization (BBO) algorithm to solve both convex and non-convex economic load dispatch (ELD) problems of thermal plants. The proposed methodology can take care of economic dispatch problems involving constraints such as transmission losses, ramp rate limits, valve point loading, multi-fuel options and prohibited operating zones. Biogeography deals with the geographical distribution of biological species. Mathematical models of biogeography describe how a…

Optimal dynamic economic dispatch of generation

Optimal dynamic economic dispatch of generation Optimal dynamic economic dispatch of generation Abstract This paper presents a review of the research of the optimal power dynamic dispatch problem. The dynamic dispatch problem differs from the static economic dispatch problem by incorporating generator ramp rate constraints. There are two different formulations of this problem in the literature. The first formulation is the optimal control dynamic dispatch (OCDD) where the power system generation has been modeled as a control system and optimization is done in…

A particle swarm optimization for economic dispatch with nonsmooth cost functions

A particle swarm optimization for economic dispatch with nonsmooth cost functions A particle swarm optimization for economic dispatch with nonsmooth cost functions Abstract: This work presents a new approach to economic dispatch (ED) problems with nonsmooth cost functions using a particle swarm optimization (PSO) technique. The practical ED problems have nonsmooth cost functions with equality and inequality constraints that make the problem of finding the global optimum difficult using any mathematical approaches. A modified PSO (MPSO) mechanism is suggested to deal with the…
