The New Control Scheme for the PV and Wind Hybrid System Connected to the Single Phase Grid

The proposed system comprises of the hybrid (PV and wind) system for 1 kw is integrated with the single phase grid. The new control scheme sine pulse width modulation (SPWM) switching with a deadbeat based PI controller is designed to a DC/AC single phase inverter. This controller is used to pure sinusoidal output voltage with low total harmonic distortion (THD), fast dynamic response control techniques and to keep the power output constant if any variation in the input from the PV and wind system occurs, and the output voltage at the grid remains constant. Even when the load varies, the sinusoidal voltage output maintains 230V(rms)with 50 Hz frequency and also low THD is 2.54%. This controller proves the stiffness and robustness characteristics for maintaining the output voltage at desired value with low harmonics.
