DC capacitance reduction in photovoltaic inverters based on PV voltage feed-forward compensation. 1 IEEE978-1-6654-3612-010.1109/EEEIC/ICPSEurope51590.2021.9584576https://academica-e.unavarra.es/handle/2454/44033In the case of photovoltaic (PV) inverters, an adequate input voltage regulation is fundamental to maximize or limit the power. When employing the traditional control, the input capacitance requires to be oversized in order to reduce the influence of the PV generator and achieve a stable control in the whole operating point. This paper proposes a voltage control method which permits reducing the capacitance by a factor of 5, thereby reducing the system cost. The control includes a feed-forward compensation of the PV voltage, making it possible to achieve a fast and stable control with a simple implementation. The proposed method is verified by simulation, showing the problems of the traditional control and the superior performance of the proposed control.application/pdfeng© 2021 IEEE.
