This use case describes how a DMS and μDMS can cooperatively control local loads (EV, water heater, water pump, battery), and local supply (battery) to reduce mitigate transformer/ secondary feeder overload, and prevent voltage violations.
There are four (4) levels of control in this use case:
1. EMS that monitors and controls generation units and DMS
2. EVECC that monitors and controls EV charging in the region
3. DMS controls a Bulk battery PCS and μDMS
4. μDMS monitors and controls a Local Battery,Home Gateway.
