Constraint Input Properties
| Name | Units | Multi-band | Default Value | Validation Rule | Key Property | Description |
|---|---|---|---|---|---|---|
| Condition Logic | - | False | 0 | In (0,1) | False | Logic used in combining conditions associated with the constraint |
| Decomposition Method | - | False | 0 | In (0,1) | False | Method used to decompose constraints between LT Plan/MT Schedule and MT Schedule/ST Schedule |
| Feasibility Repair Weight | - | False | 0.01 | False | Weight applied to relaxing the constraint in feasibility repair. Lower values mean less penalty to relax the constraint. -1 means the constraint cannot be relaxed. | |
| Formulate Upfront | Yes/No | False | 0 | In (0,-1) | False | If constraints should all be formulated upfront rather than checked iteratively. |
| Include in LT Plan | Yes/No | False | -1 | In (0,-1) | False | If the constraint is modelled in the LT Plan phase. |
| Include in MT Schedule | Yes/No | False | -1 | In (0,-1) | False | If the constraint is modelled in the MT Schedule phase. |
| Include in PASA | Yes/No | False | 0 | In (0,-1) | False | If the constraint is modelled in the PASA phase. |
| Include in ST Schedule | Yes/No | False | -1 | In (0,-1) | False | If the constraint is modelled in the ST Schedule phase. |
| Include in Uniform Pricing | Yes/No | False | 0 | In (0,-1) | False | If the constraint is enforced in the unconstrained phase of uniform pricing. |
| LHS Type | - | False | 0 | In (0,1,2) | False | Action applied over left-hand side coefficients |
| Max RHS | - | False | 1E+30 | False | Maximum allowed value when RHS is calculated dynamically | |
| Min RHS | - | False | -1E+30 | False | Minimum allowed value when RHS is calculated dynamically | |
| Penalty Price | $ | True | 0 | False | Price for violating the constraint where the special value of -1 indicates that no violation is allowed. | |
| Penalty Quantity | - | True | 1E+30 | ≥0 | False | Penalty quantity |
| Price Setting | Yes/No | False | -1 | In (0,-1) | False | Flag if the Constraint penalty function can set price |
| RHS | - | False | 0 | False | Constraint RHS constant | |
| RHS Constant | - | False | 0 | False | Right hand side RPN constant | |
| RHS Custom | - | False | 0 | False | Right hand side value over any custom period (000) | |
| RHS Day | - | False | 0 | False | Right hand side each day (000) | |
| RHS Hour | - | False | 0 | False | Right hand side each hour | |
| RHS Month | - | False | 0 | False | Right hand side each month (000) | |
| RHS Week | - | False | 0 | False | Right hand side each week (000) | |
| RHS Year | - | False | 0 | False | Right hand side each year (000) | |
| Scalar | - | False | 1 | >0 | False | Scale the constraint by dividing left and right hand sides by this factor |
| Sense | - | False | 0 | In (-1,0,1) | False | Constraint sense (less than or equal to, equal to, greater than or equal to) |
| Unit Commitment Mode | - | False | 0 | In (0,1,2) | False | Controls how the constraint is handled during unit commitment |
| Wildcard Mode | - | False | 1 | In (0,1,2) | False | Controls whether or not the Constraint is copied when it is associated with a wildcard membership. |
| x | - | True | 0 | False | Value to pass-through to solution | |
| y | - | True | 0 | False | Value to pass-through to solution | |
| z | - | True | 0 | False | Value to pass-through to solution |
