Find fraction of capacity that switches on/off more than N times a year for different N #32

This will tell us how realistic the MO module's results are. For example: if nuclear power plants are switching on/off every hour for the start-scenario, we have a problem.

In order to assess the realism of the on/off times of the new MO module, I have done the following 'analysis' (NL, 2050, start scenario):

1) Find durations of the 'production events' of all dispatchable producers 2) Multiply each event (effectively a un-interrupted stretch of time) with the available capacity of the producer 3) Add all events for all dispatchables

The result is the following chart:

The duration of the events is plotted on the x-axis (in log scale). The y-axis shows the fractional cumulative production of electricity.

From this chart you can see that:

1) Events with duration < 10 hours account for less than 10% of the total production. This seems reassuring to me! 2) About 25% of dispatchable production is due to plants that are always running (spike at 8760). Does not seem crazy either...

@AlexanderWirtz @JAlsem can you check/validate these numbers? This is something that the Sytse Jelles's of this world should know right?
