TTC Workshop on EMC Standardization 2011 S2-2 Activities in Focus Group on Smart Grid in ITU-T Tsuyoshi Masuo NTT Energy and Environment Systems Laboratories 7 March 2011 1
What is Focus Group? Focus Group(FG) is created by ITU T to provide an additional working environment for the quick development of standards in specific areas A.7 defines the objective and the establishment rules of FG Topics of FG sometimes spread across multiple Study Groups in ITU-T FG has much flexibility and discretion. Membership (Non ITU-T member can also join), leadership, financing, and types of deliverables. Deliverables themselves from FG can not be ITU-T recommendation. usually short-lived (basically 1 year term) Establishment of FG Smart Established further to ITU-T TSAG(Telecommunication Standardization Advisory Group) agreement at its meeting in Geneva, 8-11 February 2010 TSAG is the parent group of this Focus Group Focus Group on Cloud Computing(FG Cloud) was also established at the same TSAG meeting Scope and objectives Overview To identify potential impacts on standards development To investigate future ITU-T study items and related actions To familiarize ITU-T and standardization communities with emerging attributes of smart grid To encourage collaboration between ITU-T and smart grid communities including other SDOs and consortia. 2
Details of Scope and Objectives (from ToR of FG Smart) Response to environmental issues (from Rationale of ToR) The term smart grid is used for a concept of intelligent electricity networks aiming to save energy and to reduce CO2 emissions. In WTSA-08 Resolution 73 (Information and communication technologies and climate change) ITU-T called for the development of appropriate Recommendations within its mandate and competency in order to support the reduction of CO2 emissions and the impacts of climate change. ITU-T s role A smart grid concept will need harmonized support from telecommunication/ict and electric power technologies and may result in the need for flexible network and service capabilities to accommodate demands. Smart grid principles may also be applied to the telecommunication/ict system itself, consisting of networks and service platforms, in the course of providing services with more efficient use of energy not only for the core network and access domains but also for home networks. The objective of the Focus Group is to collect and document information and concepts that would be helpful for developing Recommendations to support smart grid from a telecommunication/ict perspective. Therefore, the objective is limited to the telecommunication/ict aspects of smart grid, i.e., things like the standardization of metering aspects of smart meter devices and work within the responsibilities of energy standardization bodies are out of scope. 3

Conceptual Model of Smart Grid extracted from the NIST Smart Grid Framework and Roadmap V1 document, shows a conceptual model of Smart Grid, consisting of seven major functional area call domains and the information flows between these domains, as well as the flow of electricity from power sources through transmission and distribution system to the customers. Distributed Power Generation is currently under consideration as new required capability in Smart Grid (not shown in the figure above) 7

Key Elements of Smart Grid Services/ Applications Communication Energy Markets: Distributed energy resource aggregation, wholesaler & retailer marketing, dynamic pricing, trading, market management Customer: Store, manage energy usage and generation (EMS); Home, building, industrial energy automation; metering Generation: Bulk generation, control, traditional energy generation, and renewable energy storage Operation: Distributed network operation: various SCADA, monitoring/control General operation: asset management, meter data management Transmission & Distribution: Distributed energy generation (including wind, solar, thermal); Distributed storage, substation & local distribution network monitoring and control Service Provider: Customer management, billing/ account management, home management, and building management Information Access (Data Syntax and Semantic) Communication Network (Architecture: Home/ Access/ Neighbour Area/ Wide Area; Measures: QoS & Security) Customer Domain: Meter, Customer Appliance, Distributed Energy Resource, Electric Vehicle, Customer Premise Display, HAN Gateway Distribution Domain: Data Collector, Field Devices, RTU/IED, Sensor Operation Domain: Transmission SCADA, ISO/RTO SCADA, Distribution SCADA, Management Stations (i.e., EMS, DMS). Market/ Service Provider Domains: Servers and Network Equipments Bulk Generation and Transmission Domains: Plant Control, Electric Storage, Transmission, Substation/ Control This figure was derived from ETSI s 3 layer model The Services/Applications plane refers to systems, including computers, programs, data bases, people, and operational supports to manage the applications as described in the uses cases for the Smart Grid. The Communication plane refers to the information structures and networking that enables communications between Services/Applications and entities in the Energy plane. The Energy plane refers to the devices, sensors, and controllers that provide information to the Services/Applications plane, and receive command to effect control of devices in the Energy plane. 9

Future Plan (from the agreement of TSAG meeting in Feb 2011) FG Smart Grid continues until December 2011 No new JCA or GSI on Smart Grid would be established for the moment; the JCA- IoT (Internet of Things) and the JCA-HN (Home Networking) should consider the aspects of Smart Grid relevant to their Terms of Reference. The matter of JCA and GSI would be revisited after the FG Smart Grid had concluded its work. FG Smart Grid should complete its first five deliverables (Overview, Use Cases, Requirements, Architecture and Terminology) by the end of June and then deliver them to all study groups for their review. The formal handover of all documents to the relevant study groups will take place when the FG Smart Grid is closed. In order to accelerate the process, the relevant study groups are encouraged to review these deliverables and to report back to the next TSAG meeting. ITU-T should strengthen the partnership with other SDOS such as IEC, ISO and IEEE (e.g. by organizing a joint workshop) The future of FG Smart Grid will be discussed at the next TSAG meeting in January 2012. 13
