Offering flex capacity, given a schedule

[nhoening]

Based on a computed schedule, it can be useful to offer flex capacity, for eventual activation on short notice. E.g. an aFRR market. First use case: somebody (a DSO, an aggregator) has a specific change request.

This could at first be a function, and later also an endpoint (possibly two sub-issues).

At first, we should be able to answer the question: Is there enough headroom for a specific request (of time window and capacity)?
That has a yes/no answer, but by running a second schedule with an additional constraint, we might also get at the estimated costs of such a change, which would be crucial to set a bid price, or decide if an offered compensation is acceptable.

Further work: Generating a range of options, which can be offered. Possibly using the same approach, but with assumptions on step size, etc.

How would this be used for imbalance / aFRR opportunities? I believe the market-connected actors for both need available capacity, at least to decide on short notice. That is what this functionality can in principle provide.

Note that the scheduling results already include the expected costs for each commitment, which should facilitate computing the cost difference between two schedules.
