SGAM – a reference model to escape the smart grid chaos
The Smart Grid Architecture Model (SGAM) can be used • to ensure a common understanding between different stakeholders, • to enable a structured analysis of Smart Grid use cases, • to visualize and compare different approaches to Smart Grid
architectures, paradigms, roadmaps and viewpoints, • to identify standards and standardization gaps.
SGAM is a tool to cope with the complexity of Smart Grids developed by the European Smart Grid Coordination Group.

Bulk generation e.g. coal, gas, nuclear, large RE
Infrastructure that transports electricity
Infrastructure that distributes electricity to customers
DER directly connected to the public distribution grid
The premises include industrial, commercial and home facilities including PV, EV, storage

e.g. generators, transformers, circuit breakers, overhead
lines, cables, electrical loads
Equipment to protect, control and monitor the process e.g., protection relays, bay controller, IED
e.g., energy trading, mass market, retail market
Power system control operation e.g. DMS, EMS, VPP, Microgrid
e.g., asset management, logistics, work force management, staff training,
customer relation management
Real aggregation level for field level e.g. substation automation, SCADA
