Session 1.3 energy, smart homes & smart grids: towards interoperability for demand side flexibility using saref and saref4 ener

  1. 1. ENERGY, SMART HOMES & SMART GRIDS: TOWARDS INTEROPERABILITY FOR DEMAND SIDE FLEXIBILITY USING SAREF AND SAREF4ENER Laura Daniele, TNO SEMANTiCS 2017, Amsterdam
  2. 2. INTRODUCTION
  3. 3. BACKGROUND (1/2) Societal challenge: achieve higher energy efficiency >40% total energy consumption in Europe comes from residential houses and therefore home appliances Home appliances are energy using and producing products (EupPs) designed to accomplish household functions, like cleaning or cooking e.g., refrigerators, stoves, washing machines (White goods), toasters, coffee makers, air conditioners, light bulbs (Brown goods), PCs, TVs, mobile phones, cameras (Shiny goods)
  4. 4. BACKGROUND (2/2) More and more home appliances nowadays are smart appliances Highly intelligent and networked devices Complete energy consuming, producing and managing systems The goal becomes then to achieve higher energy efficiency not only at the level of individual devices, but especially at system level
  5. 5. MOTIVATION Need for open and standardised interfaces among networked devices (often from different vendors) constituting these systems Many relevant standards already exist, but not a common architecture Need to abstract from specific details of individual standards and create an abstraction layer based on a commonly agreed semantics Need for high level model- a reference ontology- that defines recurring concepts in the smart appliances domain without having to know specifics of the various standards
  6. 6. THE SMART APPLIANCES STUDY In order to create the missing abstraction layer based on a commonly agreed semantics, in 2013 the European Commission launched a standardization initiative (SMART 2013/0077) in collaboration with ETSI TC SmartM2M to create a reference ontology for the smart appliances domain (SAREF) as “interoperability language” SAREF study conducted by TNO from January 2014 to March 2015 www.sites.google.com/site/smartappliancesproject
  7. 7. SAREF BUILT FROM AN EXTENSIVE ANALYSIS OF EXISTING STANDARDS AND PROTOCOLS
  8. 8. SAREF
  9. 9. SAREF MAIN CONCEPTS
  10. 10. SAREF EVOLUTION The outcome of the Smart Appliances study resulted in the publication of the SAREF standard by ETSI in November 2015 In 2016, ETSI requested a Specialist Task Force (SFT 513) on the management of SAREF and creation of extensions in specific domains In January 2017, the first 3 extensions were published: SAREF for Energy, SAREF for Environment and SAREF for Buildings https://ec.europa.eu/digital-single-market/en/news/new-version-machine-2-machine- standard-smart-appliances-introduced-etsi
  11. 11. SAREF SPECIFICATIONS SAREF version 2 Technical Specification: TS 103 264 V2.1.1 SAREF extension investigation Technical Report: TR 103 411 SAREF for Energy (SAREF4ENER) Technical Specification: TS 103 410-1 SAREF for Environment (SAREF4ENVI) Technical Specification: TS 103 410-2 SAREF for Buildings (SAREF4BLDG) Technical Specification: TS 103 410-3
  12. 12. A multitude of other domains such as Smart Cities, Smart AgriFood, Smart Industry and Manufacturing, Automotive, eHealth/Ageing-well and Wearables, are currently on the roadmap turning SAREF into “Smart Anything REFerence ontology”, which enables better integration of semantic data from various vertical domains in the IoT A new Specialist Task Force funded by ETSI will start in October 2017 to create 3 new SAREF extensions for Smart Cities, Smart AgriFood, Smart Industry and Manufacturing SAREF ROADMAP

  17. 17. DSF STUDY
  18. 18. THE DSF STUDY TNO is currently performing a follow-up study on SAREF for the European Commission in collaboration with ESMIG and DNV-GL for “ensuring interoperability for Demand Side Flexibility” (SMART 2016/0082) https://ec.europa.eu/digital-single-market/en/blog/digitising-energy-sector- opportunity-europe
  19. 19. DEMAND SIDE FLEXIBILITY Demand Side Flexibility (DSF) indicates the flexibility on the electricity usage offered by end-consumers (i.e., the “demand side”) to voluntary change their typical electricity consumption patterns in response to market signals, such as time-variable electricity prices or incentives The implementation of DSF not only requires energy market players (such as grid operators) and energy service companies to cooperate, but also their technical infrastructures to be coupled.
  20. 20. DSF DATA FLOWS SAREF in Home Alignment needed!
  21. 21. GOAL Goal of the study is to identify gaps in standardization, recommend alignments needed to achieve DSF interoperability - especially in relation to SAREF and its extension for Energy (SAREF4ENER) - and demonstrate an integrated DSF infrastructure
  22. 22. APPROACH (1/2) Identify use cases Identify a long list of relevant standards Identify a short list of representative standards Analyse data elements defined by these standards Identify necessary alignments between data elements, especially in relation to SAREF Propose actions & solutions for alignments to SDOs Demonstrate Proof of Concept
  23. 23. APPROACH (2/2)
  24. 24. TIMELINE March-May 2017 June 2017 June-July 2017 October 2017 Identify Use Cases and data elements Identify and analyse data standards Stakeholder workshop Identify necessary alignments Implementation Dissemination & Demonstration Aug-Sep 2017
  25. 25. STATE OF STANDARDISATION SAREF in Home We have identified a long list of relevant standards and described in terms of: Standard Acronym and Full Name Issuing Organisation/ Technical Committee/ Industry Alliance Most relevant URL and other precise references Overall description Description of data elements Interface covered in the end-to-end DSF flow
  26. 26. SHORT LIST The following standards were identified as providing a good basis for further proceed with alignments: CENELEC EN 50491-11 Smart Metering CENELEC EN 50631-1 (based on EEBus SPINE) ETSI SAREF ETSI SAREF4ENER FAN EFI (input to CENELEC EN 50491-12-2) IEC 61968-9 CIM for metering IEC 61970 CIM IEC 62056 COSEM KNX specification (defined in CENELEC EN 50090) oneM2M Base Ontology
  27. 27. ALIGNEMENTS Among the short-listed standards, we identified the need for the following alignments: ETSI SAREF/ SAREF4ENER with oneM2M Base Ontology CENELEC EN 50491-11 data points with COSEM objects KNX specification with SAREF/ SAREFENER (and KNX specification with EEBus SPINE via SAREF4ENER) FAN EFI and SAREF/ SAREF4ENER IEC CIM with SAREF/ SARF4ENER
  28. 28. DEMO A demonstrator (proof of concept) of interoperability for DSF will be shown at the European Utility Week exhibition in Amsterdam on 3-5 October 2017 Demo based on the integration of SAREF with standards (from our short list) for Energy, Demand Side Flexibility, Smart Meters, Smart Appliances and Machine to Machine (M2M) communications Industry contributors to the demo are Vodafone, some meter manufacturers (providing smart meters and a Head End System), Sierra Wireless (providing a gateway and oneM2M platform) and smart appliances manufacturers from EEBus (e.g., Bosch/Siemens)
