PV and Wind generators don't follow the input generation profile

General

Hi,

When I define PSETPRCDEF values for PV and wind generators (for example, the default values are 2000 at creation), the generators follow the input profiles. However, if I set them to 0, they over-generate (exceeding their PMAXDEF values) and the PV units even generate at night. How can I resolve this issue?

Thanks

Hi @Punit_saint

Thank you for your question!

I’m assuming you have defined a PSET event with a profile for this PV object, but I’ve included some follow up questions below. The PSETPRC value is the “price” for curtailing generation, i.e. for the power output P to be less than the scheduled power output PSET. When the value of PSETPRC is 0, then the power output can be anywhere between 0 and PSET. PMAXDEF should create a hard limit above which the unit cannot generate, unless you also change the value of PMAXPRC.

If you don’t mind, I’d like to ask a few more questions to understand how you are configuring your model.

What is the value of the following default event value properties?

  • PMAXDEF
  • PMINDEF
  • PSETPRCDEF

Is the scenario you are referring to a production cost model (DCUCOPF)?

Are there any of the following events in this scenario?

  • PSET
  • PMAX
  • PSETPRC
  • PMIN

Thank you in advance!

Thanks for your reply. The issue has been resolved. I noticed that both PMAXPRCDEF and PSETPRCDEF were set to 0. After changing PMAXPRCDEF to its default value (+Inf), the PV and wind generators active power were correctly derived from the capacity factor profiles.
