Parallel operation of virtual synchronous generators and synchronous generators in a microgrid

The Journal of Engineering, 2018
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 ...
