Abstract:
Thanks to the improvements in power electronics, a higher integration of renewable energy sources into the electric grid using power converters is possible. Virtual Synchronous Generators (VSGs) seem to be a valid control solution for grid-tied inverters, guaranteeing not only virtual inertia features, but also several grid services, such as reactive grid support during faults and current harmonics compensation. This paper deals with the damping of the mechanical part of VSG models using only a damper winding in the q-axis. A comparison is made between two of the most widespread damping methods presented in literature, and the one proposed by the authors, that shows better features. An analytical model for the q-axis damper is presented, and an experimental comparison and validation are carried out on a 15kVA grid-connected inverter.
