Hello all, I'm playing with an onsite PV and battery storage system. I want to net meter the PV system, so that it provides as much power to the building as possible. If there is surplus, charge the battery. I think this is captured in the object ElectricLoadCenter:Distribution with generator op scheme type: baseload. I set the buss type to DC with inverter and DC storage, and add the inverter and converter objects. But what storage operation scheme? None of the schemes achieves the following desired control:

discharges Battery to maintain facility demand during the day (peak hours) (this works with scheme FacilityDemandLeveling), then charges battery from grid regardless of facility demand overnight (off peak) (this does not work for FacilityDemandLeveling).

Has anybody run into this problem? It seems like an obvious control strategy. use storage to shave demand during peak, and charge from grid off peak. let me know, Greg
