Achtergrond

Introductie: Uitgangspunten

Een van de voornaamste deliverables van het NEN-normalisatieplatform is de ontwikkeling van een referentie-architectuur voor Smart Grids. Daarvoor zal worden aangehaakt bij de Europese referentie-architectuur die wordt ontwikkeld door de CEN-CENELEC-ETSI Smart Grids Coordination Group. Via het NEN-normalisatieplatform Smart Grids wordt actief bijgedragen aan de Europese referentie-architectuur.

Bij de ontwikkeling van de Europese referentie-architectuur is rekening gehouden met de volgende uitgangspunten:

  • The Smart Grids Reference Architecture must be:
  • Able to represent:
    • system aspects of smart grids in a comprehensive, consistent and understandable manner
    • interoperability aspects
  • Able to locate gaps in standardization
  • Able to cope with:
    • moving targets (in regulation) and
    • evolutionary implementation of smart grids
  • In addition, it should:
    • reuse existing foundational concepts and work
    • be independent from technology and solutions

Het Smart Grid Architecture Model is gebaseerd op het EU Conceptual Model en de interoperabiliteitscategorieƫn van de GridWise Architecture Council [GWAC2008].

EU Conceptual Model Smart Grids

De Europese referentie-architectuur is gebaseerd op een conceptueel model van het Smart Grid. Het conceptueel model is gebaseerd op het model van het National Institute of Standards and Technology in de Verenigde Staten.

Voor Europa is het NIST model uitgebreid met DER (distributed energy resources).

Relatie met GWAC Stack

Business Layer:
The business layer represents the business view on the information exchange related to smart grids. SGAM can be used to map regulatory and economic (market) structures and policies, business models, business portfolios (products & services) of market parties involved. Also business capabilities and business processes can be represented in this layer. In this way it supports business executives in decision making related to (new) business models and specific business projects (business case) as well as regulators in defining new market models.
Function Layer:
The function layer represents use cases, functions and services independent from their physical implementations in systems and components. It is intended to map the use cases including actors, sub-functions and functional and non-functional requirements. Typically, a list of use cases will cover a business case.
Information Layer:
The information layer describes the information objects or data models, which are required by the use cases, function or service. These information objects or data models represent the common semantics for functions and services in order to allow an interoperable information exchange via communication means.
Communication Layer:
The emphasis of the communication layer is to describe protocols and mechanisms for the interoperable exchange of information between components in the context of the underlying use case, function or service and related information objects or data models.
Component Layer:
The emphasis of the component layer is the physical distribution of all participating components in the smart grid context. This includes power system equipment (typically located at process and field level), protection and tele-control devices, network infrastructure (wired / wireless communication connections, routers, switches, servers) and any kind of computers.
