VSG

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

Note that this is a group separate from RenGen for VSG scheduling 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, for scheduling purposes.

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
