The model specifications can be accessed through the following links. The REGFM_A1 model has already been released in major commercial transient stability simulation tools including PTI-PSS®E, GE-PSLF, PowerWorld Simulator, and TSAT. The REGFM_B1 model is expected to be released in those tools soon.
