Generalized synchronization of coupled virtual cathode generators
Bulletin of the Russian Academy of Sciences: Physics, 2014A detailed analysis is performed of generalized synchronization in unidirectionally coupled virtual cathode generators, chain simulated by a 1D PIC electron flow. Calculations of the Lyapunov exponent spectrum for PIC systems are used to diagnose synchronous behavior.

Virtual Synchronous Generator for VSC-HVDC Stations With DC Voltage Control
IEEE Transactions on Power Systems, 2023This paper presents a two-degree-of-freedom virtual synchronous generator (VSG) for converter stations that control the dc voltage. VSGs are currently being considered in applications such as high voltage dc (HVDC) links and multiterminal dc (MTDC ...

Fuzzy virtual inertia control for virtual synchronous generator
2016 35th Chinese Control Conference (CCC), 2016The virtual synchronous generator (VSG) control scheme regulates the inverter as a synchronous generator (SG). As the SG plays an important role in the conventional grid by supporting system stability, the VSG can act the same role in a micro-grid.

Synchronization Process and a Pre-synchronization Method of the Virtual Synchronous Generator
2020 4th International Conference on HVDC (HVDC), 2020Virtual synchronous generator (VSG) is the concept of controlling the grid-connected inverters to mimic conventional synchronous generators (SGs), and it is considered to be a promising method to enhance the grid inertia and power regulation ability when the renewable energy has a high penetration rate in the grid.

Virtual impedance design of virtual synchronous generation in microgrid
2014 International Power Electronics and Application Conference and Exposition, 2014The adoption of virtual synchronous generation (VSG) control can maintain the stability of voltage and frequency in power electronic interfaced mircogrid. In this paper virtual impedance is added to the VSG control strategy in order to improve the system control performance in resistive-inductive line impedance, the influence of virtual impedance on ...
