Volume 2, Issue 4, April 2013 Page 476 Abstract Economic load dispatch is a non linear optimization problem which is of great importance in power systems. While analytical methods suffer from slow convergence and curse of dimensionality particle swarm optimization can be an efficient alternative to solve large scale non linear optimization problems. This paper presents an overview of basic PSO ...

This paper presents a review of the achievements of the optimal power dynamic dispatch problem since its inception to the present. There exist two formulations for this problem in the literature. The first formulation is the optimal control dynamic dispatch (OCDD), where the power system generation has been modelled as a control system and optimization is done in the optimal control setting wit...

This paper presents the application of Genetic algorithm (GA) to solve the economic load dispatch problem of the power system. The effectiveness of the proposed algorithm has been demonstrated on two different test systems considering the transmission losses. Test system-1 includes a three generator system and test system-2 includes an IEEE 30-bus system. The results of test system-1 are compar...

The main objective of Economic Load Dispatch (ELD) problem is to schedule the connecting generating units of plant outputs, so as to fulfill load demands at minimum operating costs while satisfying all operational constraints. Economic Load Dispatch (ELD) is one of an important optimization tasks which provides an economic condition for power systems. Recently Particle Swarm Optimization (PSO) ...

Power system operation involves some kind of optimization for ensuring economy, security and stability. Economic load dispatch is one such optimization problems and it is applied for minimizing the total fuel cost. Optimizing the fuel cost is done by properly setting the real power generation from the generators in a power system. Differential evolution is a simple and efficient evolutionary al...

This paper develops an efficient and clear insight view about the application of various PSO algorithms to the economic load dispatch problem with emission restrictions as the constraint. Solution acceleration techniques in the algorithm which enhance the speed and robustness of the algorithm are developed. The power and usefulness of the algorithm is demonstrated through its application to a t...
