MVGS
Medium-Voltage Grid Simulator
Programmable Medium-Voltage Grid Simulator for Grid Simulation and Regenerative Power Testing
The MVGS Series is a high-performance programmable medium-voltage grid simulator for demanding test benches, research facilities and certification tests in the megawatt range. The systems enable realistic grid simulation, grid fault testing and regenerative high-power testing of grid-connected power electronics. With direct medium-voltage output up to 50 kV, the series is particularly suitable for PCS systems, inverters, energy storage systems, renewable energy applications and solid-state transformers. Functions such as LVRT/HVRT/ZVRT, frequency and voltage dips, unbalance simulation and harmonic generation up to the 50th order enable reproducible testing under realistic grid conditions. Thanks to four-quadrant operation, energy recovery, master-slave expansion to 20 MVA and above, as well as modern interfaces, the MVGS Series can be reliably integrated into large laboratory and industrial test environments.

Programmable Medium-Voltage Grid Simulator of the MVGS Series
The MVGS Series is a high-performance, four-quadrant programmable medium-voltage AC source for grid simulation, regenerative high-power testing, and certification of megawatt-scale power electronics.
With direct medium-voltage output up to 50 kV, scalable system power from 1 MVA to 10 MVA and expansion up to 20 MVA+, the MVGS Series is designed for demanding test environments such as energy storage PCS, renewable energy systems, solid-state transformers, microgrids, and grid-connected power electronics.
Key Benefits
For high-power renewable energy and grid-connected converter testing, the isolation concept has a direct impact on safety, dynamic performance, measurement accuracy, and compliance testing.
A front-end isolated architecture places the isolation transformer on the grid side of the simulator. This keeps the simulator output directly coupled to the device under test, reduces output-side leakage inductance, and supports highly dynamic grid simulations such as continuous LVRT and HVRT sequences.
Compared with output-side transformer concepts, this architecture avoids transformer saturation during rapid voltage ride-through events and enables more realistic fault simulation, including line-to-earth fault scenarios, insulation monitoring tests, anti-islanding tests, and grid earthing system simulations.
Typical Applications
Grid simulation and certification testing for megawatt-scale battery energy storage converters.
Validation of solar and wind power converters under realistic and degraded grid conditions.
Testing of medium-voltage solid-state transformers and advanced grid-connected power electronics.
Simulation of grid sectors, power transfer, active/reactive power flow, and grid stability scenarios.

Integration and Automation
Added Value for Industrial Users
The MVGS Series enables realistic medium-voltage grid simulation without additional external step-up transformers. This reduces system complexity, improves dynamic performance, and simplifies integration into large-scale laboratory and certification environments.
Thanks to four-quadrant regenerative operation, advanced grid fault simulation, independent three-phase control, harmonic generation, and scalable power architecture, the MVGS Series provides a future-proof platform for testing next-generation grid-connected power electronics.
