Revision history [back]

I've modeled a PV with battery storage two ways. First by having the PV and battery operate based on the whole facility's loads by setting the Generator Operation Scheme Type toBaseLoad and the Storage Operation Scheme to FacilityDemandLeveling in the ElectricLoadCenter:Distribution object. Works just as expected. But if I try to operate the object by setting it to track a particular meter it doesn't operate as expected.

If I change only the Generator Operation Scheme Type toTrackMeter the ElectricityPurchased:Facilityand ElectricitySurplusSold:Facility are exactly the same for every hour as BaseLoad. I've verified the meter does not track the whole facility's electricity.

If I change the Storage Operation Scheme to TrackMeterDemandStoreExcessOnSite I get the below error even though I have a name in the field for the meter:

** Fatal ** ElectPowerLoadCenter::setupLoadCenterMeterIndices  Did not find Meter named: in ElectricLoadCenter:Distribution named LOADCENTER

Here's how I'm specifying the object:
