Virtual synchronous generator: An element of future grids
2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010The future power system integrated a large share of distributed generation (DG) may causes a reduction of the system rotational inertia, resulting in high frequency variations with any disturbances. An additional rotational inertia will be provided to the system if many DG units combined with relative small storage systems operate like virtual ...

Virtual synchronous generators classification and common trends
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016With the increasing penetration of photovoltaic systems, conventional plants, which are based on synchronous machines, will be displaced. Inverter based photovoltaic systems behavior is quite different from traditional generators in both electrical and mechanical dynamics, and grid stability can be negatively affected.

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.

2019 IEEE Power & Energy Society General Meeting (PESGM), 2019
Virtual synchronous generator (VSG) has been proposed to mimic the synchronous generator in terms of voltage establishment and provision of virtual inertia from electric energy storage. It thus facilitates increased power electronics connected renewable penetration while maintaining the system stability.

Inertia Response Improvement in AC Microgrids: A Fuzzy-Based Virtual Synchronous Generator Control [PDF]
IEEE Transactions on Power Electronics, 2020 The absence of rotational masses from synchronous generators in converter-interfaced microgrids leads to a lack of inertia. Consequently, the system exhibits steeper frequency variations and higher frequency nadir, which may degrade the dynamic ...

Seamless transfer of virtual synchronous generator using virtual synchronizing torque controller
International Journal of Circuit Theory and ApplicationsAbstractInverter‐dependent renewable energy sources are being integrated into the grid, raising several stability‐related difficulties. This is because these renewable sources have less inertia than synchronous generators. Since the power grid's overall inertia has improved, the introduction of virtual synchronous generators (VSG) has gained much ...

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 ...

A Pre-synchronization Method for Grid-connection Based on Virtual Synchronous Generator
2019 6th International Conference on Systems and Informatics (ICSAI), 2019The inverter is simulated as a synchronous generator that is friendly to large power grid, which can improve the absorption capacity of distributed power supply. However, when virtual synchronous generator (VSG) is connected to the grid, there will be a large current shock. Therefore, this paper proposes an improved pre-synchronization control strategy

Synchronization Strategy for Virtual Synchronous Generator based Energy Storage System
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019Due to the ability to improve system inertia of converter-dominant network, virtual synchronous generator (VSG) control strategy has earned it more concern and wide application recently. However, since the VSG can establish the voltage and phase by itself, it becomes crucial for VSG to switch from islanded mode to grid-connected mode smoothly to reduce

Re-synchronization Capability Analysis of Virtual Synchronous Generators in Microgrids
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019Since distributed energy resources (DERs) are widely connected to the system resulting in the reduced inertia of microgrid, converters are controlled as virtual synchronous generators (VSGs) to emulate the dynamic response of traditional synchronous generators.
