Constraints for the pathway optimization

**Technology ID: PATHWAY_OPTIMIZATION_CONSTRAINTS**



**Technology parameters:**

| ID | Label | Unit | Behaviors | Description  |
| --- | --- | --- | --- | --- |
| DISCOUNT_RATE | Discount rate | % |  | Discount rate of the whole pathway |
|  |

**Model code:**

``` python
portfolio = Crystal.getPortfolio()
context =portfolio.getContext()
if not "InterContext" in context:
	coeWarning("The specific pathway model object is present in the context " + str(context) + ". It will be ignored as it should only appear in the intercontext for pathway optimization (useless in other cases).")
else:
	multiportfolio = Crystal.getPortfolioMap()
	coePrint('Preliminary essential checks specific to the optimization of pathway')
	runPathwayChecks(multiportfolio)
	coePrint('MO : Actualisation weights')
	discountRate = getAssetData(asset, DEFVALUE[DISCOUNT_RATE], dataName=LABELS[DISCOUNT_RATE], mustExist=True, resizePercentage=True)
	setPortfolioWeight(multiportfolio, discountRate)
	coePrint('MO: Lifetime constraints')
	setLifeTimeConstraints(multiportfolio)
	coePrint('MO: Time constraints')

	setEqualityCapacityConstraintBetweenRealizations(multiportfolio)
	coePrint('MO: Repowering constraints')
