Study of Small-signal Modelling and Control of Grid-Integrated Photovoltaic System

This paper provides small-signal system level modelling of grid-integrated photovoltaic system. The said system comprises of two staged power electronic interface (DC-DC boost converter and DC-AC inverter). Small-signal modelling and relevant feedback control scheme has been discussed in this paper. For simulation purposes, a 100-kW grid-integrated PV system has been considered and performance of the said system at different case studies has been evaluated.
