Second-Order Harmonic Reduction Technique for Photovoltaic Power Conditioning Systems Using a Proportional-Resonant Controller

Jeong, Hae-Gwang; Kim, Gwang-Seob; Lee, Kyo-Beum - In: Energies 6 (2013) 1, pp. 79-96

This paper proposes a second-order harmonic reduction technique using a proportional-resonant (PR) controller for a photovoltaic (PV) power conditioning system (PCS). In a grid-connected single-phase system, inverters create a second-order harmonic at twice the fundamental frequency. A ripple...

Digital power factor control and reactive power regulation for grid-connected photovoltaic inverter

Hassaine, L.; Olias, E.; Quintero, J.; Haddadi, M. - In: Renewable Energy 34 (2009) 1, pp. 315-321

The overall efficiency of photovoltaic (PV) systems connected to the grid depends on the efficiency of direct current (DC) of the solar modules to alternate current (AC) inverter conversion. The requirements for inverter connection include: maximum power point, high efficiency, control power...

Analysis of the effects of inverter ripple current on a photovoltaic power system by using an AC impedance model of the solar cell

Kim, Wook; Duong, Van-Huan; Nguyen, Thanh-Tuan; Choi, Woojin - In: Renewable Energy 59 (2013) C, pp. 150-157

generated by a single phase inverter. Experimental results verify that the energy conversion efficiency of a photovoltaic power … system may be significantly reduced when the 120 Hz ripple current generated by a single phase inverter is larger than a …
