The feedin sinks of DSOs are never used, resulting in high excess energy eventhough there is a feedin tariff.
This is because in C1.define_sink() the DSO feedin sinks are defined with OptimizeCap=False.

• Check where C1.define_sink() is used
• Change the attibution of OptimizeCap=False in C1.define_sink() - do there have to be any exceptions?
• Make sure only the previously unused excess energy is fed into the grid, but other functions are not harmed
