Economic Dispatch with Environmental Considerations Using Marginal Rate of Substitution Decision Approach
Abstract
In this paper, a new decision approach is proposed for the incorporation of the carbon dioxideemission constraints in the solution of the unit commitment (UC) problem. An efficient particle swarmoptimization (PSO) algorithm is used for generating the fuel cost versus emission tradeoff function forCarbon Dioxide emission; the marginal rate of substitution (MRS) is then calculated to help the managersmore rationally determi ....etc

Application of Genetic Algorithm to Economic Load Dispatch
ABSTRACT:
This paper presents an approach based on genetic algorithm to solve the economic load dispatch (ELD) problem with losses for three thermal plant systems. Genetic algorithms are adaptive search methods that simulate some of the natural processes: selection, information, inheritance, random mutation and population dynamics. This approach was tested for three thermal plant systems. The performance of Genetic Algorithm - intelligent approach (GAs) is compared ....etc

INTRODUCTION
Economic dispatch is one of the most important optimization
problems in power system operation and forms the basis of
many application programs. Conventional methods employ
the widely used Lagrangian approach. However in the case of
segmented piece-wise quadratic function, corresponding to the
valve point loading or mixed fuel fired inputs, conventional
approach fails to obtain an optimal solution. In this context,
several approaches have been proposed using non-conventional
optimization approaches, including artif ....etc

Abstract

This paper presents an adaptive Hopfield neural network (AHNN) based methodology, where the slope of the activation function is adjusted, for finding approximate Pareto solutions for the multi-objective optimization problem of emission and economic load dispatch (EELD).We have placed emphasis on finding solutions quickly, rather than the global Pareto solutions, so that our algorithm can be employed in large on-line power systems where variations in load are quite frequent. To ena ....etc

ABSTRACT
Economic load dispatch is the process of allocating the required load demand between the available generation in power system in naturally predominant in determining allocation of generation to each generation for various systems load levels.
Economic load dispatch (ELD) is an important function in power system planning and operation.ELD solutions are found by solving the conventional load flow equations while at the same minimizing fuel costs.
