Improving naming and definition of sets/parameters
The naming logic of sets/parameters is a bit ambiguous or illogical in some cases.
- suft(effSelector, unit, f, t) and sft(s, f, t)
- effGroup(effSelector) is not a group as defined in 'group' set. Typically sets named e.g. sGroup(s, group)
- up_down(param_policy) / up, down /; as a subset leads to unintuitive definition of reserve capabilities and requirements
