Common Grid Model Alignment Methodology (CGMAM)
First of all, note that the CGMAM is not a methodology in the legal sense – it is not required by the CACM Regulation and does not need to be approved by NRAs. It is also not written as if it were an EU Regulation. As for the subject matter, note that when building their individual grid models (IGMs) as input for the common grid model (CGM), TSOs have to use a consistent set of balanced net positions and balanced flows on DC lines. Otherwise the load flow calculation will not converge and it would not be possible to build a (usable) CGM. For those target time horizons for which market schedules are available (day-ahead and intraday) the schedules provide the information required. However, for some target time horizons, notably
(D-2) and (Y-1), schedules are not available. The CGMAM makes it possible to provide TSOs with a set of balanced net positions and balanced flows on DC lines even for those target time horizons for which market schedules are not available. The CGMM sets out a number of specific requirements for the CGMAM which have been transposed into the document approved by “All TSOs”.
