IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022 Virtual synchronous generator (VSG) control technique is widely used for the grid-friendly integration of renewable energy. However, when VSG is attached to a weak grid, it is prone to voltage and frequency instability, which aggravates the voltage ...

Microgrid Frequency & Voltage Adjustment Applying Virtual Synchronous Generator [PDF]
2019 International Conference on Smart Energy Systems and Technologies (SEST), 2019 The distributed generations (DG) are linked to microgrids (MGs) by power converters regularly and the MG will be in mutual interconnection with conventional power systems. The more the participation level of the converter-based DGs in the MG, the more the stability issues are seen in the MG.

Improving the Synchronous Stability Control Strategy of Virtual Synchronous Generators
Journal of Physics: Conference Series, 2023 Abstract The microgrid dominated by new energy has small inertia and weak damping, while a virtual synchronous generator (VSG) is an effective means to enhance inertia and damping to improve the stability of the microgrid. However, it also introduces power angle oscillation problems similar to that of synchronous machines.
