Modeling and Simulation of Hybrid Wind and Photovoltaic Stand-Alone Generation System

This work focuses on the modelling and analysis of a Standalone wind-PV Hybrid generation system under different conditions in MATLAB/SIMULINK environment. The proposed system consists of two renewable sources i. e. wind and solar energy. Modelling of PV array and wind turbine is clearly explained. It works as an uninterruptible power source that is able to feed a certain minimum amount of power into the load under all conditions. Power transfer was different modes of operation, including normal operation without use of battery, which gives the user-friendly operation. A control strategy regulates power generation of the individual components so as to give the hybrid system to operate in the proposed modes of operation. These two systems are combined to operate in parallel and the common DC bus collects the total energy from the wind and photovoltaic subsystems and uses it partly to charge the battery and partly to the DC load. This paper offers a useful wind-PV hybrid model which can be used for performance analysis of such systems.
