Modeling, Analysis, and Stabilization of a Single-Stage Utility-Scale Photovoltaic System with Reduced DC-Link Capacitance
DownloadFall 2020
A single-stage utility-scale photovoltaic (PV) system is usually interfaced with the host grid via a central voltage-source converter (VSC). Recently, due to their reliability, dc-link film capacitors are favored over electrolytic capacitors in grid-connected VSC applications. However, the...
