dynamic economic load dispatch is one of the most important roles of power generation’s operation and control. it determines the optimal controls of production of generator units with predicted load demand over a certain period of time. economic dispatch at minimum production cost is one of the most important subjects in the power network’s operation, which is a complicated nonlinear constraine...

Recently, population growth and resource depletion have been matched by a growing demand for self-sustaining communities. Numerous studies promote sustainable solutions to the concerns of climate change food scarcity. This study aims at creating an automated Economic Land Utilization Optimization Model (ELUOM) that identifies cost-effective agricultural practices. Soil, water & climatic cha...

A power system operation at minimum cost is no longer the only criterion for electrical power dispatch. Combined economic emission dispatch problem is obtained by considering both the economy and emission objectives with required constraints. This problem can be solving optimization techniques. Many optimization techniques are slow for such complex optimization tasks and are not suitable for on...

Effective parameters that can effect on the performance of the separation system consist of operating pressure, operating temperature, reflux ratio, and kind of produce desirable products and different sequences of splits. As take a separation system with optimal performance is dependent on optimization of above mentioned effective parameters. In generally, there are two criteria (as object fun...

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...

A low efficiency of bull fattening resulted in a decrease of beef production in Poland. One of the possibilities of the improvement of fattening efficiency is a proper choice of decisions concerning the course of a fattening process. Making the optimal decisions can be supported by means of dynamic programming (DP) models, using the hierarchic Markov process (HMP) technique. The models develope...

Particle swarm optimization (PSO) has received increasing attention in solving multi-objective economic dispatch (ED) problems in power systems because of parallel computation, faster convergence, and easier implementation. This paper presents a detailed overview of multi-objective particle swarm optimization (MOPSO) and provides a comprehensive survey on its applications in power system econom...

The rational economic load dispatch can not only save the energy, but also improve efficiency of power systems. Therefore it is important to research economic load dispatch problem. However, The problem is a complex and nonlinear optimization problem considering valve-point loading effects of generating units; it is difficult to solve the problem using traditional optimization method. Therefore...
