There are a number of constraints that will need to be introduced to the MVS.
@SabineHaas please think of possible constraints and also give a (sentence long) desctiption of the subsequent constraint.
Examples: Capacity limiter, net zero energy system, emissions, connection of transformer in/out

Ongoing list of necessary constraints (with descriptions):

• Connection of transformer in/out capacities (further discuss in Transformer objects describing in/out of a bus should be connected #24)
• Limit feed-in to avoid unbound solutions (issue Introduce feed-in limits to avoid unbound solution #1)

Details for specific constraints should be discussed in own issues as to limit this thread´s lenght.
