Wind and sunlight are the most vital and significant sources of renewable energy for harnessing electricity to meet the rapid increase in energy demand all around the world. Off-grid hybrid systems prove to be more convenient and beneficial in distributing power to the rural areas and grid isolated system as compared to an grid connected system. The conventional system coupled with the hybrid system can prove to improve the system stability and is therefore economically viable in terms of the device and storage system cost. This paper deals with the design and experimental implementation of a hybrid wind /photovoltaic (PV) system along with fuzzy logic (FL) based MPPT controller. The hybrid system is essentially based on the nature of the source, environmental condition and the number of consumers being supplied. The control scheme has been justified with both simulations as well as hardware results. The validation results have been provided, which clearly show that the proposed scheme is expected to offer an impeccable solution for application in remote areas where utility grid is neither economical nor feasible.
