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
