Dear sir

Please see my paper in my page of researchgate about the meeting electricity needs of hybrid system of wind turbine and photocell

Dear Mahmoud H Onsa can you specify the climate zone/region that we are considering?

Dear sir

Please see my paper about photovoltaic and hybrid system in my page in researchgate.

The peak load in hot arid land due to the use of air-conditioning systems excessively during daytime.

Whenever you use a PV power plant (e.g. MWs size) Integration with wind geothermal or hydro will keep production useful

Have a look at publications and links of the NEO Carbon Project:

I think that in case of PVs in arid areas we will observe a very beneficial correlation between PVs energy yield and energy demand for AC (as you said). In my opinion they have a huge potential to shave the peak load. Take a look for example at a recent paper by Sebastian Sterl et al., (http://iopscience.iop.org/article/10.1088/1748-9326/aad8f6/meta) where they proposed a new index for assessing solar-wind hybrids operation and discussed it in case of West Africa countries.

When it comes to coupling PVs with another sources I can recommend you some papers by Bo Ming and myself where analysis was performed for PV-hydropower hybrid systems.

Although I don't know how huge is the potential of hydropower in "arid regions". However, this is an interesting research direction. We (@Bartłomiej Ciapała) addressed this issue in our recently published in Solar Energy paper, where we have analysed the PV-hydrpower operation also from the water retention perspective.

Dear Mahmoud

At Elsevier you can find some papers that can help you in the development of your research.

If your institution has the signature of the base, you can access it at any time and without limitations.
