the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...
The 252Cf brachytherapy source is a spontaneous fission decay source, which is used as a neutron-emitting source. In addition to neutrons emitted from this source, gamma rays are also emitted with the average energy of 1 MeV. In this study, using the Monte Carlo N-Particle code (MCNPX), the absorbed dose rates of the neutrons, the primary gamma and the secondary gamma that generated by thermal ...
The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...
Using the renewable energy is the better option to supply demined in the standalone area. World’s most fast-growing renewable energy resource is the wind energy. One of the main disadvantages of this system, however, is that naturally variable wind speed causes power fluctuation problems at the load side. Besides, long-term storage of power generated by wind turbines is considered as a limitati...
In this paper, we study the unbalance problem of the input Direct Current (DC) voltages of the five-level neutral point clamping (NPC) voltage source inverter (VSI) used in hybrid renewable energy system. The hybrid system is composed of doubly fFed induction generator (DFIG) driven by wind turbine, the rotor is connected to three fivelevel NPC VSI feed by photovoltaic voltage source. We show p...
In residential section, Studies have shown that, along with the use of various household consumption management techniques, the so-called hubs of energy can also be used to improve the performance and management of home energy management. In each electrical energy system, customers are aiming to minimize their energy costs. In this paper, it can be seen that in each home a home-made residential...
Comparison of Single-stage and Two-stage Tubular SOFC-GT Hybrid Cycles: Energy and Exergy Viewpoints
In this work, single-stage and two-stage tubular solid oxide fuel cell (SOFC)/gas turbine hybrid cycles are comparatively examined from the energy and exergy viewpoints. For this purpose, mass, energy and exergy balances are applied to all components of the cycles. The behavior of tubular solid oxide fuel cell modeled in this study is validated with the experimental test data of tubular SOFC de...
