Modular multilevel converter/mmc/virtual synchronous generator/vsg control

Modular multilevel converter/mmc/virtual synchronous generator/vsg control
Grid type inverter
By using technologies such as virtual moment of inertia and virtual impedance, it can participate in power grid frequency and voltage regulation, suitable for various working conditions such as weak current networks and microgrids.
Basic operating conditions: AC: 6.6kv DC: 11kv N: 22
Simulate voltage sag/frequency sag in the power grid from 0.4s to 0.9s
MMC can have the characteristics of a grid type inverter, which supports the frequency/voltage of the power grid by adjusting P and Q.
Equipped with circulating current suppression, submodule capacitor voltage balance control, current inner loop control, and VSG control
Adopting NLM modulation
