This use case describes the hierarchical control of EMS, EVECC, DMS and μDMS to coordinate EV charging to enable simultaneous mitigation of renewable energy on system frequency and mitigation of feeder level disruptions (P, Q).
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 that controls the Bulk Battery PCS and μDMS
4. μDMS that controls the Local Battery, Home Gateway.
