Solar photovoltaic-wind power systems

RO and hybrid solar photovoltaic-wind power systems have been also designed and implemented (Houcine et al., 1999 Weiner et al., 2001 Mohamed et al., 2006). Recently, Folley et al. (2008) proposed a combined wave-power and RO desalination plant in which seawater can be directly... 

The choice of a renewable energy source to power a hydrogen fuel cell system will depend on the geography, climate and other resources of the location. I have chosen photovoltaics as the example power source for hydrogen production because it is available to more people than either geothermal, wind, or tidal. For a person without much technical skill, solar power is easier to implement than wind power. It is also less costly up front and not as dependent on location as the other RE power sources... 

Hybrid Renewable Energy System - A renewable energy system that Includes two different types of renewable energy technologies that produce the same type of energy for e.g., a wind turbine and a solar photovoltaic array combined to meet a power demand. 

Microgeneration technologies include small wind turbines, solar photovoltaic (PV) systems, small-scale hydro and micro CHP (combined heat and power) systems,... 

Besides, they could be used to stabilize the power grid which has to face instabilities due to factors such as power arising from photovoltaic solar systems or wind power plant of private persons and companies. 

Separately derived system—A premises wiring system whose power is derived from a battery, from a solar photovoltaic system, or from a generator, transformer, or converter windings, and that has no direct electrical connection, including a solidly connected grounded circuit conductor, to supply conductors originating in another system. 

The interface between the renewable source and RFC system must match their current and voltage, which differ for solar and wind systems. Photovoltaic solar systems generate direct current, which may be used directly by the electrolyzer if their polarization curves are well matched, otherwise a DC/DC converter may be needed. Wind generators typically generate AC, so the interface must include an AC/DC inverter, similar to the electrolyzer s regulated voltage power supply.
