Managing Demand Supply mismatch
I don't know where the problem stems, but it seems it is not a technical problem related to ETSAP-TIMES. If there is a large amount of zero variable cost renewable generation in the system, then power curtailment and (and zero marginal value) may occur in some timeslices.

Anyway, one suggestion for a modeling issue to check:
  • How do you define ┬áthe "technical minimum for operation"? If you are using lower bounds on process availabilities (NCAP_AF(LO)), then remove those, and use ACT_MINLD instead. ACT_MINLD will allow the technologies to be also shut down seasonally (or even daily), if they are not needed. The solution is not a "least-cost" solution if you are forcing thermal generation in the model although the plants could be shut down instead.
