Enhanced Power Decoupling Strategy for Virtual Synchronous Generator [PDF]

IEEE Access, 2020
Power coupling caused by high impedance ratio and nonzero power angle is a crucial issue for virtual synchronous generator (VSG), which may result in output power error, slower power response and even invalid operation. To solve this issue, a novel enhanced power decoupling method by using virtual steady-state synchronous impedance (VSSI) and current ...

A Novel Pre-Synchronization Control for Grid Connection of Virtual Synchronous Generator

Elektronika ir Elektrotechnika, 2020
The virtual synchronous generator (VSG) introduces rotational inertia and damping through the droop control to take part in frequency regulation of the grid. By building the VSG model, the VSG controller, including both the frequency controller and the excitation controller, are analysed and designed.

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.
