VSG

Renewable generator with virtual synchronous generator (VSG) control group.

Note that this is a group separate from RenGen for VSG dispatch study.

Common Parameters: u, name, idx, bus, gen, Sn

Common Variables: Pe, Qe

Available models: REGCV1, REGCV2

REGCV1

Voltage-controlled converter model (virtual synchronous generator) with inertia emulation.

Here Mmax and Dmax are assumed to be constant, but they might subject to the operating condition of the converter.

Notes

• The generation is defined by group StaticGen

• Generation cost is defined by model GCost

• Inertia emulation cost is defined by model VSGCost
