Smart Grid ad hoc Meeting Information - January 2010 Authors: Date: 2010-1-17 Name Company Address Phone email 5488 Marvell Lane, Santa Clara, CA, 95054 +1 (321)427-4098 bkraemer@ marvell .com Bruce Kraemer Marvell Abstract: Information on Smart Grid of interest to WG11 – January 2010 Bruce Kraemer, Marvell

  2. Agenda • High Level Questions • National SmartGrid Perspective • EPRI View • What has previously transpired? • NIST PAP#2 • What is happening over the next two months • Longer term goals, events, project plans. • Observations/Assumptions/Conclusions/Discussion • Steps 802.11 needs to take to fit into the Smart Grid plan Bruce Kraemer, Marvell

  3. High Level Questions • What is happening in Smart Grid arena? • Is 802.11 properly positioning its existing and pending standards and amendments for acceptance in SG? • Participation in key Smart Grid activities • Are there any identifiable additions or changes that should be considered to make 802.11 more useful in SG domains? Bruce Kraemer, Marvell

  4. Observation/Assumption/Conclusion #1 • Dozens of organizations are involved but our focus is primarily on: • NIST SGIP • http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/PriorityActionPlans • IEEE P2030 • Discussion: Bruce Kraemer, Marvell

  5. Observation #2 • There is a substantial amount of material already created by NIST and other long term SmartGrid participants that describe Application Domains and Use Cases. • There is no need for 802.11 to duplicate this work. • There is a need to make these data flow models more complete/quantitative . • Task 1 of NIST PAP#2 intends to supply this information. • Discussion: Bruce Kraemer, Marvell

  8. Other examples of Requirements • Example #1 - description of need for Home Area Network • http://osgug.ucaiug.org/sgsystems/openhan/HAN%20Requirements/OpenHAN%20Specification%20Dec.ppt Bruce Kraemer, Marvell

  9. Observation #3 • The NIST PAP#2 Tasks deserve considerable attention • Discussion: Bruce Kraemer, Marvell

  10. NIST PAP Overview (1) Priority Action Plans (PAPs) Described • PAPs arise from the analysis of the applicability of Standards to the Use Cases of the Smart Grid. PAPs include identified experts in relative SDOs, known as the PAP Working Group Management Team. • Specifically, a PAP addresses either: • A gap where a standard or standard extension is needed: • The need for meter image-download requirements is an example of a non-existing standard needed to fill an identified gap. • An overlap where two complementary standards address some information that is in common but different for the same scope of an Application: • An example of this is metering information where CIM, 61850, ANSI C12.19, SEP 1&2 all have non-equivalent methods of representing revenue meter readings. • PAPs should only be created when the SGIP determines there is a need for interoperability coordination on some urgent issue. The PAPs themselves are executed within the scope of the SDOs and Users Groups that sign up for tasks that implement the plans. The duty of the SGIP is to facilitate this process, ensure that all PAP materials are publicly available in real time on the TWiki (that is, not entirely within the domain of the SDOs which prevents all but membership access), and provides guidance when the participants in the PAP are at odds or unsure of its goals. Bruce Kraemer, Marvell

  11. NIST PAP Overview (2) • It will often be the case that the SDOs that are executing the PAP tasks (as part of the PAP Working Group Execution Team) diverge from the original intent of the PAP. This is due to their natural, and correct, orientation towards their own specific goals and needs. The PAPs arise from the broader stakeholder involvement in the Smart Grid problem space and such has identified goals that come from this broader scope. In these cases, the parties are brought together under the auspices of the SGIP and an attempt to resolve the differences is pursued. The possibility could arise where this is not sufficient to move the PAP forward. In this case the PAP WG or the SGIP can: • Revise the PAP to accommodate the concerns of the implementers, or, • Can redistribute the tasks of the PAP to organizations more in line with the needs of the scope of the PAP. • Rescind the PAP judging that it is no longer in the interest of the SGIP to pursue. Bruce Kraemer, Marvell

  12. NIST PAP2Wireless Communications for the Smart Grid (6.1.5) • http://collaborate.nist.gov/twiki-sggrid/bin/view/SmartGrid/PAP02Wireless • Abstract: • This work area investigates the strengths, weaknesses, capabilities, and constraints of existing and emerging standards-based physical media for wireless communications. The approach is to work with the appropriate standard development organizations (SDOs) to determine the characteristics of each technology for Smart Grid application areas and types. Results are used to assess the appropriateness of wireless communications technologies for meeting Smart Grid applications. Bruce Kraemer, Marvell

  13. NIST PAP#2 • Description: • Review existing documentation and ongoing work to assess the capabilities and weaknesses of wireless technologies operating in both licensed and unlicensed bands and to develop guidelines on their use for different Smart Grid application requirements. Bruce Kraemer, Marvell

  14. NIST PAP#2 • Objectives: • Identify requirements for use of wireless technologies for the Smart Grid. • Identify guidelines for effectively, safely, and securely employing wireless technologies for the Smart Grid. • Identify approaches to define the strengths and weaknesses of candidate wireless technologies to assist Smart Grid design decisions. • Analyze co-channel interference issues and develop coexistence guidelines for operation in unlicensed bands. • Identify key issues to be addressed in wireless assessments and development for the Smart Grid. Bruce Kraemer, Marvell

  15. NIST PAP#2 • Why: • Wireless technologies are one of many types of media that could meet many Smart Grid requirements by enabling access where other media are too costly or otherwise not workable. • However, different types of wireless technologies also have different availability, time-sensitivity, and security characteristics that may constrain what applications they are suitable for. • Therefore, different wireless technologies must be used with knowledge of their varying capabilities and weaknesses in all plausible conditions of operation. This work provides objective information on the appropriateness of use. Bruce Kraemer, Marvell

  16. NIST PAP#2 • Where: • Wireless can be used in field environments across the Smart Grid including generation plants, transmission systems, substations, distribution systems, and customer premises communications. • The choice of wireless or non-wireless, as well as type of wireless must be made with knowledge of the appropriate use of the technology. Bruce Kraemer, Marvell

  17. NIST PAP#2 – Next Meeting • PAP 2 session at OpenSG Users Group, San Fransisco, February 4, 2010: • A face-to-face meeting will take place on February 4th, 2010, starting at 8am until 3:00pm. This meeting is collocated with the OpenSG User Group meetings in San Fransisco during the week of February 1, 2010. Information about registration and the hotel venue can be found at: • http://osgug.ucaiug.org/sf2010/default.aspx Bruce Kraemer, Marvell

  18. NIST PAP#2 Tasks • Task 1: Segment the smart grid and wireless environments into a minimal set of categories for which individual wireless requirements can be identified. • Task 2: Develop Terminology and definitions. • Task 3: Compile & communicate use cases and develop requirements for all smart grid domains in terms that all parties can understand Bruce Kraemer, Marvell

  19. NIST PAP#2 Tasks • Task 4: Compile and communicate a list of capabilities, performance metrics, etc. in a way that all parties can understand. - Not quantifying any standard, just defining the set of metrics. • Task 5: Create an inventory of wireless standards and their associated characteristics (defined in previous task) for the environments identified in task 1. • Task 6:Perform the mapping and conduct an evaluation of the wireless technologies based on the criteria and metrics developed in task 4. Bruce Kraemer, Marvell

  20. NIST PAP#2 -Network Information • Both IP and wireless communications priority action plans include as a first task the development of network requirements for Smart Grid applications. • Identifying these requirements is key in order to develop guidelines for the use of IP and wireless communications in the context of the Smart Grid. Bruce Kraemer, Marvell

  21. NIST PAP#2 Functional Requirements • http://collaborate.nist.gov/twiki-sggrid/pub/SmartGrid/PAP01InternetProfile/SG_Communications_funct-reqs_v1-draft.xls Bruce Kraemer, Marvell

  22. NIST PAP#2 – Task 5 Guidance • Task 5 calls for the collection of an inventory of wireless technologies, based on the parameters and metrics developed in Task 4, to be filled by each SDO. • The purpose of the row entries in the wireless capability matrix NIST_PAP2-_Wireless_Characteristics-IEEE802-v_02.xls developed in Task 4 is to allow high level assessment of the suitability of particular wireless standard based technologies for use in various applications and domains of the Smart Grid. • Since many of the parameters in the matrix have dependencies on each other, e.g. data throughput, range and mobility, the matrix should be filled out by providing a consistent set of parameter values, rather then best case values for each parameter. • By a “consistent set” we mean that one picks some “operating point” for the technology and provides parameter values (for those that depend on operating point) that are consistent. For example, maximum data rate will not be delivered at maximum range. A column entry is expected to provide values for the error rate, range, throughput, mobility and other interrelated parameters consistent with the chosen operating point. It would be appropriate to complete more than one column for an individual technology to display the results for more than one operating point. Bruce Kraemer, Marvell

  23. NIST PAP#2 – Task 5 so far Bruce Kraemer, Marvell

  24. Observation #4 • The Matrix rows were adequate for collecting information from SDOs. • Discussion: • The rows do/do not require further modification. Bruce Kraemer, Marvell

  25. Observation #5 • The operating points used were chosen by the SDOs. • This was adequate for collecting first response information. • Discussion: • The operating point should be “standardized” to allow useful comparisons. Bruce Kraemer, Marvell

  26. Observation #6 • Within WG11, reporting on Smart Grid activities in an ad hoc forum once time block per session is adequate. • Discussion: Bruce Kraemer, Marvell

  27. Plans for Thursday • One more session Thursday am1 • Topics to be addressed: • 1. • 2. • 3. • 4. Bruce Kraemer, Marvell
