Decentralised
​
The Level 1 DER Interface is managed directly by the Level 2 Controller.
Centralised (Direct)
​
The Level 1 DER Interface is managed directly by the Level 3 Controller.
Centralised (Indirect)
​
The Level 1 DER Interface is managed directly by the Level 3 Controller but via the SCADA/DMS Control channels.
Centralised (Hybrid)
​
The Level 1 DER Interfaces are managed directly by the Level 3 Controller and also the SCADA/DMS System.
