Stability Investigation of Three-Phase Grid-Tied PV Inverters with Impedance-Based Method …
This paper presents stability investigations of three-phase grid-tied photovoltaic inverter systems using the impedance-based method. Impedance models (IMs) are established considering different control loops, and passive elements. IMs with a current control in both synchronous and stationary frames are established and compared. Impacts of different …
