摘要
This paper proposes a single-stage single phase grid-tied photovoltaic (PV) supply system (SPGPSS). An H-bridge voltage source converter (VSC) is controlled using an enhanced third order generalized integrator (ETOGI). The ETOGI is used to extract the grid synchronization signal and an active component of load currents. The ETOGI works efficiently under presence of grid voltage disturbances such as dc-offset, harmonics or sag/swell. The performance of the proposed control scheme is verified on prototype developed in the laboratory and control algorithm is implemented on TMS320F28379D controller. Its effectiveness is validated under dynamic change in solar irradiations and change in loads. Its performance is found satisfactory under standard test conditions.
