Development of high frequency (Supraharmonic) models of small-scale (<5 kW), single-phase, grid-tied PV inverters based on laboratory experiments

Abstract

Abstract There is a growth of high frequency (HF) emissions in the range of 2–150\xa0kHz (also known as Supraharmonics) in electricity distribution networks, primarily due to the increasing number and capacity of AC grid connected equipment having power electronic interfaces. Although PV inverters are a major HF source in electricity distribution networks, PV inverter models that are suitable for HF emission studies are yet to be developed. To this end, a generic method that can be used to develop HF models of small-scale (
