RenGen#
Renewable generator (converter) group.
See SynGen for the notes on replacing StaticGen and setting the power ratio parameters.
Common Parameters: u, name, bus, gen, Sn
Common Variables: Pe, Qe
Available models: REGCA1, REGCP1, REGCV1, REGCV2
REGCA1#
Renewable energy generator model type A.
Implements REGCA1 in PSS/E, or REGC_A in PSLF and Powerworld.
Volim is the voltage limit for high voltage reactive current management, which should be large than static bus voltage (Volim > v), or initialization error will occur.

REGCP1#
Renewable energy generator model (REGC_A) with PLL.
A PLL device can be specified for estimating the phase angle at the coupling
bus through the pll parameter:
If
pllis not given, the accurate bus angle will be used.If
pllis not a valid PLL device, the program will error out.The program does not check if the provided
pllactually measures the bus on which the converter is at.
One needs to carefully tune the PLL parameters to match the desired performance.
All other remarks for REGCA1 apply.

REGCV1#
Voltage-controlled VSC with VSG control.
Includes double-loop PI control and swing equation based VSG control. Voltage measurement delays are ignored.
Notes#
Extreme care needs to be taken when coordinating the PI controller parameters.
Setting the primary frequency control droop
kwcan improve small-signal stability.The droop
kvfor voltage control (pu voltage / pu Q change), if used, needs to be chosen carefully. In most cases,kvshould be a very small positive value if not zero.

REGCV2#
Voltage-controlled VSC with VSG control.
The inner-loop current PI controllers are replaced with lag transfer functions.
Notes#
To avoid small-signal stability issues, one take extreme care in setting the
PI control gains Kpvd, Kivd, Kpvq, and Kivq, and the emulated
inertia M and damping D.
