Transient Modeling and Verification of Current Source Photovoltaic Virtual Synchronous Generator

With the promotion of virtual synchronization technology, photovoltaic (PV) virtual synchronous generator (VSG) gradually develops from micro-grid field to bulk power grid. Active control of frequency response and voltage regulation of VSG can support the grid operation friendly. Based on control principle of current source PV VSG, the PV VSG transient model was established in this paper, which was validated to be accurate based on multi-test condition data, and it is provided basic support for stability analysis of VSG connected with bulk power grid.
