Abstract
Wind and solar energy sources should be taken in account as the creative solution for assuasive the energy crisis and reduction process of the CO2 emissions. Furthermore as an these energy resources for electrical power sourcing capable to work in smart grid system. For a long time, It is also be known the renewable energy sources are characterized by the unsustainable and unstable .these disadvantages are the main challenge to gathering of the energy supplying by renewable sources and the smart grid. The thesis presents the suggested solutions for overcome the challenges. which results about the effect of atmospheric turbulence, which is the main factor affecting energy production in renewable sources such as PV and wind farm (WF).
