Recently, increase in the cost of fossil fuels and taking into consideration the environmental effects of exploiting them, caused many researchers and governments to find some ways to make use of renewable energies more cost-effectively. Solar energy is a category of renewable energies which could be harvested via several technologies. One of the most practical methods is using parabolic trough...

developing electrical energy is one of the basic needs for development, so equipping the rural regions and villiages is one of the main responisiblities of thirdworld countries. in this study, we used economic evaluation indexes to compare electrification to baghtaj village by power grid expansion and application of solar photovoltaic systems. economic evaluation indexes suggests that in the ab...

Current trends in energy production suggest that renewable energy will play an important role in future electricity generation. Among renewable sources, solar power is considered to be one of the most promising alternatives which is well supported by the rapid increase of Solar Thermal Power Plant installations worldwide. Solar energy (so as renewables) however is plagued by the intermittent na...

Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...

A strategy is described for the construction of a reference model design solar chimneys that includes variations in geometry and materials chimney's components. The will be developed from dynamic simulations transient state chimney under irradiation real conditions. based on artificial neural networks (ANNs) generalization properties allowing predictions multiple geometries chimney. can serve a...

The application of gain-scheduled control to a pilot-scale solar power plant is described. A eld of parabolic collectors focus the solar radiation onto a tube where oil is pumped through in order to collect the solar power. The control problem is to keep the temperature of the oil leaving the eld at its desired value by manipulating the oil pump ow rate. It is shown that gain-scheduling can e e...
