The major problem of wind turbines is the great variability of wind power production. The dynamic change of the wind speed returns the quantity of the power injected to networks. Therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. In deregulated power systems, the scheduling problem has various objectives than i...

The integrated energy system (IES) plays a key role in conservation and emission reduction. In order to realize the low-carbon economic dispatch of IES, current studies usually utilize fixed ladder-type pricing mechanism-based carbon unit cost (CEUC) optimal model. However, those mechanisms fail take emissions levels into account, relevant parameters, such as interval length, are hard set. tack...

This paper presents the application of an enhanced Particle Swarm Optimization (EPSO) combined with Gaussian Mutation (GM) for solving the Dynamic Economic Dispatch (DED) problem considering the operating constraints of generators. The EPSO consists of the standard PSO and a modified heuristic search approaches. Namely, the ability of the traditional PSO is enhanced by applying the modified heu...

The energy flow characteristics of Combined Cooling, Heating and Power (CCHP) system are analyzed in detail and the energy flow function is proposed for its two operational strategies: thermal load dominant mode and electrical load dominant mode. In order to improve its economic and environmental efficiency, an optimal economic and environmental dispatch model is built, which includes the fuel ...

Climate change as the greatest environmental challenge facing the world today. Power stations play a major role in greenhouse gas emissions. Nearly 21.3% of green house gases are emitted by power plants alone. The main sources of greenhouse gases are due to burning of fossil fuels and deforestation leading to higher carbon dioxide concentrations. Normally CO2 in the atmosphere is removed by mix...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. wca is used to solve complicate...
