Virtual Synchronous Machine fault ride through capability with Reactive Power Synchronization
2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2020This paper presents the fault ride through capabilities of a proposed Virtual Synchronous Machine (VSM) control strategy for a Voltage Source Converter (VSC). In a grid which is evolving towards so-called smart grid, it is necessary to prove that power electronic converters have a good performance facing critical grid events. They must fulfill all grid

Design And Implementation of Virtual Synchronous Machine
2018 International Conference on Computing, Electronic and Electrical Engineering (ICE Cube), 2018The increased penetration of renewable sources into the electric grid has opened new horizons for researchers. In this context, maintenance of system stability is the most important objective which needs an immediate consideration. The reason for such keen interest is that the renewable energy sources do not behave as the conventional power plants ...

Algorithm for Virtual Synchronous Machine Phase Resynchronization
2018 9th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2018In this paper, the idea of operating parallel inverters to mimic the dynamic stability of a synchronous generator (SG) is investigated when the inertia and damping constants are differed. These inverters are virtual synchronous machines (VSM) due to the replication of the inertial dynamics inherent to the SGs. Instead of using a conventional Phase-Lock

Damping Provision by Different Virtual Synchronous Machine Schemes
2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2020The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds

A synchronization controller for grid reconnection of islanded virtual synchronous machines
2015 IEEE 6th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2015The control of power electronic grid interfaces as Virtual Synchronous Machines (VSMs) is emerging as a suitable approach for converters in distributed power systems. VSM implementations including an internal model of a virtual inertia can also inherently allow for both grid-integrated and standalone applications.

Virtual Impedance Design Considerations for Virtual Synchronous Machines in Weak Grids
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020Most renewable energy sources (RESs) are interfaced to electricity grids via voltage-source converters (VSCs). To facilitate the integration, the controllers based on the emulation of synchronous generators have been increasingly used. This control technique is commonly referred to as Virtual Synchronous Machine (VSM) and recent studies have shown that

Electrical Engineering, 2021
A new multifunctional inverter control structure is proposed in this paper by embedding the harmonic and unbalance regulators into the virtual synchronous machine (VSM). While including the harmonic and unbalance regulators, inverters can provide support to the grid not only as VSMs, but also as active power filters (APFs) and unbalance conditioners ...

Damping Effect of Virtual Synchronous Machines Provided by a Dynamical Virtual Impedance
IEEE Transactions on Energy Conversion, 2021Virtual synchronous machines (VSMs) emulate the swing equation for grid synchronization and inertia provision. Usually, a large damping coefficient is necessary in VSMs to provide equivalent damper winding effect, which is, however, not aligned with the fact that the physical swing equation of synchronous generators (SGs) contains only a small ...

Virtual synchronous machine method in renewable energy integration
2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2016The virtual synchronous machine (VSM) method is a power electronics based approach which was first introduced by Beck and Hesse in 2007 for renewable energy integration modeling. This method controls grid-connected renewable energy sources as electromechanical synchronous machines, which makes renewable energy sources behave as conventional power ...
