Selecting between static and dynamic inertia constraints
As noted by @CODWYER , there is currently no clear way to select whether the model uses the static (q_inertiaMin) or the dynamic (q_rateOfChangeOfFrequencyUnit and q_rateOfChangeOfFrequencyTransfer) inertia constraint. For the q_inertiaMin constraint to become active, it is enough to have ROCOF, defaultFrequency and restype_inertia defined. For the other constraints to become active, it is enough to have ROCOF, defaultFrequency and unit_fail / portion_of_transfer_to_reserve defined. The selection between the constraints should be made clearer. What would be the best way to do that? Should we add new parameters p_groupPolicy(group, 'static_inertia') and p_groupPolicy(group, 'dynamic_inertia')?
