Operational reserve constraint with energy storage

[pz-max]

• Here the GenX publication. Page 31 last & page 32 first paragraph talks about energy storage play a role for reserves (incl hydro etc).

• Our current PyPSA-Eur implementation does not consider energy storage https://github.com/PyPSA/pypsa-eur/blob/3fba8dae3ee5aa98b3eaad038acc3e1445620749/scripts/solve_network.py#L733-L790

Energy storage should be considered. However, because not all markets might consider storage as a reserve contributor, it should be implemented as an option.

Implementation idea:

• Avoid introducing if conditions
• Write in config a boolean (True/False aka. 1/0) for storage addition in the reserve constraint
• Add terms to the lhs and rhs for the constraint (see here). rhs= old terms + new term * boolean
• One challenge will be to properly understand what term to add on the lhs and rhs side... Good documentation for the new term will be essential
