The start-up and shut-down variables are defined as binary variables and calculated from the difference of two adjacent status variables, which are also binary. It would be sufficient to define...

Up for discussion. PR #208 added the `unit` as an attribute to the Bus component. Currently, any unit conversions are handled in the efficiency attributes of links. For example, ```py...

Currently, cost attributes `capital_cost` and `marginal_cost` always refer to `bus0`. In the same way, `efficiencyX` refers to the output of `busX` per `bus0`. It has been suggested a couple of...

### Headline Add option for `n.plot()` to return an animation over snapshots as a video. ### User Interface Details to be fleshed out, but it could work like this: The...

Generators and links already support unit commitment constraints (ramping, start-up, shut-down). This could be expanded to storage units (i.e. their power dispatch variables).
