I am not sure what kind of clarification is needed here. As far as the TIMES model generator is concerned, defining the PCG is basically the sole responsibility of the modeller. Under VEDA you have some automation that might be helpful, but it is always safest to define the PCG explicitly.

I am sure that by now you have also read the documentation which explains the PCG (Part II, section 2.2.1 Definition of the Reference Energy System (RES)):
Part II, section 2.2.1 Wrote:The activity variable (VAR_ACT) of a standard process is in most cases equal to the sum of one or several commodity flows on either the input or the output side of a process. The activity of a process is limited by the available capacity, so that the activity variable establishes a link between the installed capacity of a process and the maximum possible commodity flows entering or leaving the process during a year or a subdivision of a year. The commodity flows that define the process activity are specified by the set prc_actunt(r,p,cg,u) where the commodity index cg may be a single commodity or a user-defined commodity group, and u is the activity unit. The commodity group defining the activity of a process is also called Primary Commodity Group (PCG).
User-defined commodity groups are specified by means of the set com_gmap(r,cg,c), which indicates the commodities © belonging to the group (cg). Once a user-defined commodity group has been defined, one can use it for any processes for defining attributes that require a commodity group (not only for the definition of the process activity, but also for other purposes, e.g., in the transformation equation EQ_PTRANS), as long as the members of the group are valid for the particular process and the process characteristic to be defined.
Usually, it would make no sense defining NRG or MAT as the PCG, because normally only the input(s) / output(s) should define the activity, not both (excluding storage). Again, here VEDA has some shortcuts (NRGI, NRGO, MATI, MATO etc.). User-defined groups are needed when the individual commodities or the available shortcuts are not sufficient, for example, if you have three NRG outputs, but only two of them should be defining the activity (according to the model designer, i.e. you).
