Introduction

The Smart energy Grid Architecture Model (SGAM) is a three-dimensional architectural framework that can be used to model interactions (mostly exchange of information) between different entities located within the smart energy arena:

  • Business axe (domains)
  • Architecture axe (zones)
  • Interoperability axe (levels)

NOTE : the IEC SRD 63200 will be available by mid 2020

A bit of history

SGAM was born at the time of the European mandate M/490.

Its formalization happens first through the CEN-CENELEC-ETSI Smart Grid co-ordination group (now called SEG-CG as Smart Energy Grid co-ordination group).

The main objectives were to help all different stakeholders, not that much used to work together (Generators,TSOs, DSOs, DERs, Home/building/industries), to share a common framework, with a specific emphasis on interoperability.

SGAM for multi-energies

Since its original publication, the SGAM has been extended in order to support more than just electricity, i.e other energy fluids such as heat and power.

SGAM Domain

A set of roles involved in the energy industry, considering that the whole industry is partitioned into business domains: (Bulk) Generation, Transmission, Distribution, DER(Distributed Energy Resources) and Customers’ Premises.

SGAM Zone

Hierarchical level of the system architecture from the energy market places, down to the physical power equipment, considering that the whole chain is partitioned into 6 zones: Market, Enterprise Operation, Station, Field and Process

SGAM interoperability levels

Conceptual layer derived from the interoperability layers as described in the GridWise Architecture Council (GWAC) model, such that the whole set of interoperability layers is divided into 5:

  • Business
  • Function
  • Information
  • Communication
  • Component

SGAM main usages

The SGAM is a tool which can be used efficiently in many different situations as depicted in the figures below :

  • Mapping a Smart Energy system on different layers such as component, communication or information
  • Mapping standards as the appropriate layers (component, communication, information …)
  • Mapping standardisation entities scopes

Reference documents

To come soon – the IEC SRD 63200 – at CD level 2019-01 ‒ should come with:

  • The extension to interfaces to other energies
  • A formal UML model and ontology (owl)
