  3. PAP 14 Objectives Develop strategies to expand and integrate MultiSpeak, IEC 61850, IEC 61968, IEC 61970, IEEE PC37.237 (Time Tagging), IEEE PC37.239 (COMFEDE) and the future IEEE Common Settings file format for Smart Grid Applications. Develop a summary of information required from the power system for various Smart Grid applications. Map that information with the already defined models from MultiSpeak, IEC 61970, IEC 61968-11, and IEC 61850. Coordinate with the SDOs to extend the existing models.

  4. PAP 14 Objectives Continued Identify setting information that is required to perform an automatic verification of the power system configuration to prevent failures due to mis configurations. This information shall include both settings in the devices as well as parameters of the power network that need to be available for verification. – long-term issue (two-year effort) and is Use Case-based; step one: IEEE group work PSRC H5; Coordinate with the SDO to extend the existing standards as a result of defining next generation Smart Grid T&D functions.

  19. Use cases for the Self-healing Grid n.markushevich@smartgridoperations.com www.smartgridoperations.com 12/2/2010

  20. Active Distribution Networks (ADN)High penetration of: • Load dependent on • Real-time pricing • Embedded DER • Demand Response • PEV • Technology • Other • Large DER/ES/MG dependent on • Weather • Technology • Maintenance • Price • Volt/var control mode and settings • Protection settings • Load Shedding Remedial Action Schemes dependent on • Operations of MG (connected – autonomous) • Load behavior (see above) • Overlapping with other schemes • Changing priorities • Pre-armed settings • DMS applications dependent on • Objectives • Available tolerances • Available controls

  21. Aggregated Load of ADN at Transmission Buses • Significant deviations from conforming (typical, proportional) load shapes • Significantly changing load-to-voltage dependences due to • Embedded DER • DER with Volt/Var control capabilities in different modes • DER/MG with voltage protection • Intermittent operations of DER • Changing combinations, mode of operations, and settings of voltage and var controlling devices • Demand Response with different PF • Significantly changing load-to-frequency dependences due to • Embedded DER • DER/MG with frequency protection • Intermittent operations of DER • Changing number of DER on-line • Different frequency control capabilities • Short-tem predictability (minutes)

  22. Architecturally Critical Information Exchanges for the SHG • SCADA data • PMU data • Data on the behavior of Active Distribution Networks under normal and emergency conditions

  23. Aggregation of Information on ADN in Transmission Bus Load Model (TBLM) • Aggregated models of • Distributed Energy Resources and their behavior under normal and emergency conditions • Controllable and uncontrollable reactive power resources • Demand Response and its behavior • VVWO behavior • PEV performance • Aggregated MW and Mvar dependences on voltage • Aggregated MW and Mvar dependences on frequency ( • Dispatchable real and reactive loads via: • VVWO • Demand Response • DER control • Emergency Load Shedding

  24. ExampleNear-real-time analysis of potential islanding

  25. Pre-arming of Islanding requires • Prediction of real power balance in the potential island (frequency) • Prediction of reactive power balance in the potential island (voltage) • Islands are formed to minimize the load-generation imbalance • Prediction of the reaction of the Active Distribution Network (~ 20% of DER, Micro-grids, Demand Response, VVWO, etc.) • Adaptive near-real-time analyses based on • Transmission model update • PMU data • Reaction of the Active Distribution Network

  26. Two-area load-rich potential island (before the separation) Area 1 Area 2 DER1/MG DER2/MG Pt-jQt P-jQ G11 G12 G21 G22 VVWO DR Load 2 Load 1 UFLS, UVLS for Sub-Area 1 UFLS, UVLS for Sub-Area 2 Disconnected Connected

  27. Two-area load-rich island (after the separation) Area 1 Area 2 DER1/MG DER2 /MG P-jQ G11 G12 G21 G22 VVWO DR Load 2 Load 1 UFLS, UVLS for Sub-Area 1 UFLS, UVLS for Sub-Area 2 Disconnected Connected

  28. Questions to be answered by the analyses of potential islanding • Is the load-generation imbalance manageable during the island situation? • Will DER separate due to frequency or voltage, or both – with or without load? • Will the weak tie be overloaded? • Is the load shedding sufficient, etc.? • Are the priorities of load shedding adequate? • How will the situation develop during prolong islanding? • What is the latency and the possible contribution of Demand Response and VVWO? • What is the risk (uncertainty) factor? • What re-coordination of protection and RAS would be needed?

  29. ??? Questions Continued • What is the expected cold-load pickup? • What is the latency and possibilities of DER resynchronization? • What should be the priorities of load restoration? • The TBLM should contain information that is needed to answer these questions.

  30. Information and control flows Distribution domain T&G domains AMI Subst. LTC, Shunts, SVC PMU DER/ES/MG TBLM Processor EMS SE CA SCD Pre-arm Restora-tion ……… DR Topology model DMS DOMA VVWO FLIR Emerg. apps TBLM PEV Load model Processor Topology Processor RAS SCADA Data DSCADA Control T&G devices

  31. Priority Use Cases for Operations of SHG, addressing the cross-cutting over domains • Creation and updates of Transmission Bus Load Model • State Estimation • Contingency Analyses with prioritization based on PMU and TBLM • Security Constrained Dispatch – for preventive measures • Pre-arming of Corrective Measures • Restoration after emergency Need to use PMU and TBLM

  33. USE Case List and Tool Completion Strategy • Need PAP 14 subgroup to help integrate prospective use cases from variety of sources and cull the list down for the priority tool • Identify Sources of Transmission Operations Use Cases • Categorize into Hierarchy • Populate Tool with Use Case Listings for Priorities • Forward Priority Tool to SDO’s, Consortia, and T&D DEWG

  37. Extra: SGIP Rosetta Stone Project Development

  38. Rosetta Stone Background Background and Need Several PAPs Working on Application Level Communications (Semantics) within their respective application space Several Standards Exist and In Development to codify semantics for Smart Grid Generic Need for Harmonization/Integration/Unification of Standards for Application Level Communications Need to avoid replication of work within SDOs working on PAPs Objectives Evaluate Approaches and Methods to appropriately Harmonize/Integrate/Unify Smart Grid Standards Develop common methods and tools to H/I/U existing and developing standards across different operating environments Develop Contributions to SDOs and User Groups as Appropriate
