Guidelines for use of real-code in EMT models for HVDC, FACTs and inverter based generators in power systems analysis

A Joint Working Group of CIGRE B4.82 and IEEE (with more than 100 members), developed and released a standard method for interfacing of control and protection models to power system simulation tools, including “realcode” (ie the actual source code used in field hardware) and other generic or user-written models. This allows identical simulation models to be used in many power system programs, and helps improve upon issues of compatabiltiy, accuracy and confidentiality.
