Parallel operation of virtual synchronous generators and synchronous generators in a microgrid
Aiming for integration of a large‐scale of distributed generators (DGs) such as photovoltaic into the microgrids, the virtual synchronous generator (VSG) control concept has been developed. By this concept, DGs based on inverters can exhibit the characteristics of synchronous generators (SGs) such as the inertial, damping, and droop functions and can ...

Virtual synchronous generators dynamic performances [PDF]
In this paper, dynamic performances of virtual synchronous generator are investigated. The virtual synchronous generator is based on the synchronverter (VSG) concept which is an inverter that mimics a synchronous generator (SG). The real and reactive power delivered by VSGs connected in parallel and operated as generators can be automatically shared ...

Influence of control parameters on synchronization stability of virtual synchronous generator
Different from the synchronization mechanism of synchronous generators, the non-synchronous generators must be synchronized with the grid through a controller. Generally, the virtual synchronous generator (VSG) control strategy is adopted for this purpose.
