Transformer Formulate Upfront

Units:Yes/No
Mode:Input Only
Multi-band:False
Default Value:False (0)
Validation Rule:False (0) or True (-1)
Key Property:No
Description:If constraints should all be formulated upfront rather than checked iteratively.

Transformer Formulate Upfront controls when the thermal limits for the Transformer are added to the mathematical programming problem. The setting can take these values:

False (value = 0)
Constraints are added only when the Flow on the Transformer exceeds the Rating.
True (value = -1)
Constraints are added during simulation initialization.

In general it is more efficient to add constraints only as needed but in some cases performance maybe improved by adding the constraints upfront, avoiding additional iterations.
