When analysig the sector coupled energy systems that we simulate, it can be interesting to know how interconnected the different energy vectors actually are. For that we want to introduce a novel key performance indicator: The degree of sector coupling (DSC). There is already a description on the RTD.

• The function needs to be finalized, so that it can be executed from E0.
• Pytests for function must be be added
• Benchmark test should be added
• Think about potential outcomes and meanings of a degree of sector coupling of, eg. 0, 0.5, 1 or >1, and document them in RTD
