FPGA-based controller for mitigation of the 100 Hz oscillation in grid connected PV systems

This paper illustrates a new control strategy for reducing the photovoltaic (PV) voltage oscillations at twice the grid frequency in double-stage single-phase PV inverters. It is based on the analytical calculation of the duty-cycle compensation which is able to lead to an almost constant PV voltage...

Zusammenfassung:This paper illustrates a new control strategy for reducing the photovoltaic (PV) voltage oscillations at twice the grid frequency in double-stage single-phase PV inverters. It is based on the analytical calculation of the duty-cycle compensation which is able to lead to an almost constant PV voltage. The work is focused on the optimization of the performances of the FPGA-based digital implementation; the proposed approach is validated by means of experimental results.
