A portable proton exchange membrane (PEM) fuel cell operates at room temperature, has an energy density which is 4 to 6 times larger than that of a Li-ion battery, and thus is a promising next generation power source for power-hungry portable devices. However, in spite of the high energy density, fuel cells have limited power capacity and cannot respond to sudden changes in the load. Thus, a sy...

in this paper, optimal design of hybrid solar-wind- diesel energy system with battery storage for reliable load in arsoon village in ardabil is presented. the village has 35 households that mean daily energy consumption is estimated 63.4 kwh. in this design optimization is implemented, considering loss of power supply probability (lpsp) index for reliable load providing, with minimum total cons...

Alternative Energy is becoming a popular and an essential energy resource in the current century. This paper investigates the effect of using a hybrid microgrid system in Langkawi and Socotra Islands. Configuration of the optimal hybrid system is selected based on the best components and its sizing with appropriate operation strategy to provide a cheap efficient, reliable and cost effective sys...

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

In this paper, the hybrid photovoltaic-thermoelectric generator (PV-TEG) combined dynamic voltage restorer (DVR) system is proposed for power quality disturbances compensation in a single-phase distribution system. The stable and precise level of input essential smooth trouble-free operation electrically sensitive loads which are connected at utility side to avoid malfunctions. context, PV-TEG ...

this research deals with axial and oblique impact crash tests on simple and hybrid composite tubes. axial and oblique impact tests have been generated on simple and hybrid composite tubes with one, two and three layers. a drop test rig was used to conduct the experiments. furthermore, in order to gain more detailed knowledge about the crash process, finite element simulations of the experiments...

Untapped pine needles with high potential for energy generation in the hilly area are not only a waste of resource but also increase the chance of environmental hazards as forest fires and GHG emission. This study is conducted to propose a new hybrid system (PV/Wind/Biomass) using abundant pine needle resource as a replacement of existing roof-mounted PV/wind hybrid system and analyse the feasi...
