One of the important energy consuming sectors of the country is buildings. In this research, we use the energy audit of the Atisaz complex in Tehran to evaluate the economic benefits of energy saving measures.  We evaluate measures such as: using the automatic damper, replacing the active existing chiller with the solar absorption one, using intelligent boiler-room and replacing the existing li...

The impact of different energy storages on power systems has become more important due to the development of energy storage technologies. This paper optimizes the stochastic scheduling of a wind-based multiple energy system (MES) and evaluates the operation of the proposed system in combination with electrical and thermal demand-response programs and the three-mode CAES (TM-CAES) unit. The prop...

electrical sensitivity of a boron nitride nanotube (bnnt)  was examined toward c2h5oh molecules by using density functional theory (dft)  calculations . it was founding that the adsorption energy(ead) of ethanol on the  pristine  nanotubes  is about -51.5 kj / mol, but when  the nanotube has been doped  with si and al atoms , the adsorption  and recovery time changed and the sensitivity of nano...

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...
