The issue of harmonic injection from utility integrated photovoltaic systems. I. The harmonic source

The role of the photovoltaic (PV) system as a harmonic noise injector is investigated and the various aspects of PV power converter design that affect harmonic injection are discussed. It is concluded that small, residential-sized units, if greatly proliferated, are the greatest source of concern to utilities, as larger systems are typically designed to the interconnected utility's specification. Techniques are available to limit the harmonic output of these smaller units without resorting to bulky, expensive filtering.<
