now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
As a key economic element, energy plays an important role in the development of societies. Economic growth and its urgent need for energy highlight the need for optimal energy use. Wind energy is an energy source that has become an increasingly common source of electricity. In this study, socio-economic impacts of the cost of electricity generated by wind power plants were assessed with Iran as...
As an effective means of displacing fossil fuel consumption and reducing greenhouse gas emissions, plug-in electric vehicles (PEVs) and plug-in hybrid electric vehicles (PHEVs) have attracted more and more attentions. From the power grid perspective, PHEVs and PEVs equipped with batteries can also be used as energy storage facilities, due to the fact that, these vehicles are parked most of the ...
Iran is ranked as the ninth largest greenhouse gas producer in the world, with an annual emission of nearly 180 million tons of CO2 by thermal power plants.. The purpose of this research is to simulate and optimize the optimal economic and environmental load dispatch and a portfolio of efficiency improvement strategies on both supply and demand sides in MT1, MT2, and EEP scenarios in using the ...
introduction: the aim of this study was to investigate the scanning electron microscope (sem) analysis of tooth surface irradiated by different parameters of er:yag laser. methods: 15 caries-free extracted human third molars were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 2.5 w, energy: 250 mj); group 2(power: 3 w, energy: 300 mj); gro...
In recent years, due to the economical advantages, environmental friendly attribute and renewable generation cycle, the renewable power sources have gained a great attention as a main alternative to traditional power resources. However, as a main deficiency, a renewable power system has low reliability, because of the stochastic and the un-deterministic generation pattern of these resources. In...
: In this paper, the operation of a future distribution network is discussed under the assumption of a multi-carrier microgrid (MCMG) concept. The new model considers a modern energy management technique in electricity and natural gas networks based on a novel demand side management (DSM) which the energy tariff for responsive loads are correlated to the energy input of the network and changes ...
the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...
nowadays, energy plays an important role in the economic and community development of country. consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. among the different power generation technologies, steam power plants make a significant contribution to power generation in iran, with a share of 47 % of electricity g...
