The human demand for electricity and fresh water is ever increasing. Due to the nature of hydropower and its economic, social, and environmental benefits, hydropower will be an important contributor to the energy mix of the future. Isolated areas, severely underdeveloped regions, disaster-stricken zones, and remote military outposts have one common need: readily available and efficient means of...
Nowadays, optimal integration and utilization of renewable energy sources (RES) are of the most challenging issues in power systems. The wind and solar generation units' maximum production may or may not occur at peak consumption times resulting in non-optimal utilization of these resources. As a solution to this problem, energy storage systems (ESS) are embedded in networks. However, the power...
The energy crisis in recent years has led politicians and major countries around the world to take energy issues differently from the past and replace fossil fuels with renewable energies, including hydroelectricity, to reduce and save energy, controlling supply and demand energy and reduction of pollutant emissions has been widely welcomed. Accordingly, the present study investigates the impac...
In this paper, a novel real time pricing design is presented for Demand Response (DR) programs. A Load Serving Entity (LSE) is responsible to provide energy for flexible loads, inflexible loads and thermal loads. The LSE consider operation conditions of system and uncertainty of renewable energy resources and it designs a Real Time Price (RTP) demand response. The inflexible and thermal loads c...
differential scanning calorimetry (dsc), temperature programmed desorption mass spectrometry (tpd-ms) and small angle neutron scattering (sans) were used to investigate co2 uptake by the wyodak coal. adsorption of carbon dioxide on wyodak coal was studied by dsc. the exotherms evident at low temperatures are associated with the uptake of co2 suggesting that carbon dioxide interacts strongly wit...
With increasing levels of renewable energy in power systems, the coordination different types dispatchable resources, such as coal-fired plants, hydropower storage and electric vehicles, has become more important than before. To optimally dispatch these operating units, quality forecasting results becomes increasingly for operation systems. In this study, an ultra-short method was proposed phot...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Electricity production is a challenging issue when it comes to mitigating greenhouse gases (GHG) emissions without risking development goals. Non-renewable energy sources, as fossil fuel burning, account for most of the global energy production (68% in 2007) and are responsible for most of the anthropogenic GHG emissions to the atmosphere (40%, International Panel on Climate Change IPCC, 2007)....
Energy as a geopolitical factor has gained a special occasion in power games of the world and access to energy resources has become a strategic importance for all levels of hierarchy of global power. Hormozgan province is one of the industrial provinces of Iran and this subject has caused to has been growing energy consumption in the province. Limited fossil energy resources and the problems of...
Differential scanning calorimetry (DSC), temperature programmed desorption mass spectrometry (TPD-MS) and small angle neutron scattering (SANS) were used to investigate CO2 uptake by the Wyodak coal. Adsorption of carbon dioxide on Wyodak coal was studied by DSC. The exotherms evident at low temperatures are associated with the uptake of CO2 suggesting that carbon diox...
