Smart Grid Architecture
The software behind a modern power grid: SCADA/EMS for transmission, ADMS for distribution, smart meters, DER management and the customer portal.

What this diagram shows
- SCADA and ADMS monitor and control the network in real time
- Distributed energy (rooftop solar, batteries) is managed centrally
- Meter data drives billing and demand response
Prompt used
Smart grid architecture: grid operators use an energy management system (EMS/SCADA) for transmission and an advanced distribution management system (ADMS) for feeders and substations. A DER management system controls rooftop solar and batteries, the meter data management system receives AMI data, a demand response service sends peak-time signals, and customers see usage in a portal. Field devices connect over an OT network with IEC 61850 and DNP3.
