Active power limitation applied earlier than configured threshold

[Andrés Fernández]

Hello,

I have noticed a behavior when simulating a PV plant with an active power injection limit at POI. In the output CSV file, the power seems to start being limited slightly before reaching the configured threshold in the simulation settings.

I am attaching a screenshot of both the CSV output and the configuration parameters for reference.

Could you please clarify why this limitation is applied earlier than the set value? Is this an intended behavior in the model or is there a specific setting that I should adjust?

Thank you for your support.

Best regards,

Hello,

Indeed, this is not the expected behavior. Since the grid limitation is applied at the Pnom, we have observed that in certain situations—when the MPPTs operate under very different conditions—this may lead to results that do not perform as intended.
