Transient Analysis of Microgrids With Parallel Synchronous Generators and Virtual Synchronous Generators

IEEE Transactions on Energy Conversion, 2020
In recent years, the increasing penetration of distributed generation in microgrids challenges the control and coordination of energy resources. Especially in microgrids with virtual synchronous generator (VSG)-controlled converters and conventional synchronous generators (SG), the inherent inertia difference (i.e., the VSG and SG) results in a poor ...
