Renewable Hybrids Grid-Connection Using Converter Interferences

Use of Renewable Energy power sources is the best possible solution today to reduce increasingly risk of global warming and the most important type
of renewable is Wind and Solar energies which are the most efficient. The green power generation resources are used power generators in Distributed
Generation (DGs) sources that are in direct relation with the use of micro capacity power generating units of power system that are installed in
distribution level of power systems or all segments that loads and energy consumers are located. Hybrid systems vary in models. The best hybrid
model available today is combination of grid connected wind turbines and solar PV cells that can compensate each other in the grid connected state. In addition, solar cells provide electricity required in day-time while wind turbines compensate the power needed in the night period. Solar cells are consisted
of a series of assembly of different cells together to form a flat photovoltaic system to absorb the photons and generate electricity by electrons energized in the circuit. On the other hand, Systems for conversion of energy of wind use PM Synchronous Generators. Recently, wind turbines are even enhanced to use
VSD drives to provide the machine the ability of generation in cases that rotational speed varies with changes in speed of wind. The simplified version of
the solar-wind hybrid system is provided and Simulations are done to confirm expectation outcomes of this connection.
