Microgrid Controller to Support PV
Penetration

• large 2 MW PV and battery system 1 MWh
• in the future 8 MW of PV and full microgrid
• export limit to utility of 1 MW
• supervisory controller to support this high renewable
penetration

Demand charge as well as peak TOU cost reductions are important drives for DER
and microgrid adoption. Will this be also true for CCAs with unbundled tariffs and
maybe less flexibility to influence TOU and demand related costs?
