INTRODUCTION
The proposed hybrid renewable green energy scheme has four key subsystems or components to supply the required DC and AC electric loads.
The first subsystem includes the renewable generation sources from Wind turbine and Fuel Cell.
The second is the interface converters used to connect the renewable energy generators to the common DC collection bus, where the generated energy is collected.
The third device represents the added inverter between the common collection DC bus and the added AC bus interface to feed all AC loads before integration with the public grid.
The fourth subsystem comprises all controllers including the modulated power filter.
Integrated (Wind-FC) Green Energy UtilizationScheme for Village Electricity
The scheme uses a primary common DC bus collection with an added secondary common AC bus for feeding any AC loads and public grid interface.
The proposed hybrid green energy scheme is digitally simulated for different operation conditions and load excursions.

The simulation results show that the effects of changing operating conditions are compensated by controlling the DC-DC chopper, which interfaces the FC stack to the common DC bus.
Similarly the effect of wind speed variations is compensated by controlling the AC-DC rectifier converter, which interfaces the wind generator to the common DC bus.
