Grid connected Wind-Photovoltaic hybrid system

This paper presents a modeling and control strategies of a grid connected Wind-Photovoltaic hybrid system. This proposed system consists of two renewable energy sources in order to increase the system efficiency. The Maximum Power Point Tracking (MPPT) algorithm is applied to the PV system and the wind system to obtain the maximum power for any given external weather conditions. The generator side converter is controlled by the Field Oriented Control (FOC). This approach is used to control independently the flux and the torque by applying the dand q-components of the current motor. The utility grid side converter is controlled by the VoltageOriented Control (VOC) strategy which is adopted to adjust the DC-link at the desired voltage. The simulation results using PSIM software environment prove the good performance of these used techniques to generate sinusoidal current waveforms. This current is synchronized with the grid voltage. Moreover, the DC bus voltage is perfectly constant because only the active power is injected into the grid. Simulations are carried out to validate the effectiveness of the proposed system methods.
