The current paper offers the solution strategy for economic dispatch problem in electric power system implementing ant lion optimization algorithm (ALOA) and bat (BA) techniques. In network, (ED) is a short-term calculation of optimum performance several electricity generations or plan outputs all usable generation units from energy produced to fulfill necessary demand, although equivalent uneq...

Reactive power dispatch plays a main role in order to provide good facility secure and economic operation in the power system. In a power system optimal reactive power dispatch is supported to improve the voltage profile, to reduce losses, to improve voltage stability, to reduce cost etc. This paper presents a brief literature survey of reactive power dispatch and also discusses a comparative s...

Original scientific paper Economic Load Dispatch problem has been previously solved successfully with swarm techniques. However, power systems with complex behaviours still await a robust algorithm to be developed for their optimization more precisely. Economic Dispatch problem with constraints such as generator limits, total power demand, ramp rate limits and prohibited operating zones, makes ...

Economic load dispatch (ELD) is an important optimization task in power system. It is the process of allocating generation among the committed units such that the constraints imposed are satisfied and the energy requirements are minimized. There are three criteria in solving the economic load dispatch problem. They are minimizing the total generator operating cost, total emission cost and sched...

Received Sep 12, 2016 Revised Oct 20, 2016 Accepted Nov 6, 2016 In India Electrical Energy is generated mainly Coal based Thermal Power stations and hydro Electric Power Stations. The main aim of power generating company is to provide good quality and reliable p ower to consumers at minimum cost. The problem of Combined Economic and Emission Dispatch deals with the minimization of both fuel cos...

The fundamental objective of economic load dispatch is to operate the available generating units such that needed demand satisfies lowest generation cost and also complies with various constraints. With proper power system operation planning using optimized limits, it possible reduce generation. To fulfill needs objectives, can help plan electrical system. optimize problems, classical new evolu...

Preventive maintenance scheduling and economic dispatch, have found prominent positions in the operation of power systems. A new heuristic algorithm based on the tabu search has been proposed as a solution method to the maintenance problem. This algorithm seeks to satisfy an objective function that can either maximize or minimize spinning reserve capacity of the power system over the entire pla...
