2 Where is Oak Ridge, TN? U. S. DEPARTMENTOF ENERGY

3 ORNL is DOE s largest multipurpose science laboratory $1.04 billion budget 4,000 employees 3,000 research guests annually Nation s largest unclassified scientific computing facility Nation s largest science facility: the $1.4 billion Spallation Neutron Source Nation s largest concentration of open source materials research Nation s largest energy laboratory $300 million modernization in progress

4 ORNL performing R&D to assist DOE in improving electric grid reliability Power Delivery Testing Facilities Advanced Materials Computation & Modeling HTS - 2G wire & components Transmission Monitoring Power Electronics Test facility Power Electronics HTS cable & subsystems Next-Gen components Computational Modeling & Controls DE Systems (DECC) Energy Storage Ensure the Reliability & Security of the Nation s Grid Reduce Transmission Congestion Improve Power Quality Reduce Major Outages Improve Restoration Times National Security OAK RIDGE NATIONAL Micro-grids LABORATORY U. S. DEPARTMENT OF Reconfigurable ENERGY Grid Critical Infrastructures Distributed Energy Integration

5 ORNL Simulation and Modeling ORNL-led team selected to build the National Leadership-class Computing Facility Cray X1 evaluation completed Expanded from 256 to 512 processors Global ocean simulation: 50% higher simulation throughput than on Japanese Earth Simulator for equal number of processors Plan is to increase capability to 1 petaflop (1,000 trillion calculations per sec) Research Areas include: astrophysics - supernova research climate and carbon research- climate simulation Is there an opportunity to utilize this resource? computational biology fusion simulation - plasma energy research industrial innovation - combustion simulation materials research - precise calculations of molecular structures nanomaterials theory

6 Developing tools to improve situational awareness of the electric grid DOE Office of Electricity Delivery and Energy Reliability sponsored effort Response to the devastating hurricanes in 2005 Coordinate federal response to natural disasters or major events ORNL, in partnership with TVA, developing real-time grid visualization tool Initially assess status of transmission lines in the Southeast Kevin Kolevar discusses DOE's hurricane preparedness efforts with Red Cavaney of the American Petroleum Institute and Bud Danenberger (right) of the Updated Department August 29, 2005 of the 8:20 Interior's a.m. EDT Minerals Management Service. 230 kv blue 500 kv green EDGAR Two platforms have been developed Google Earth ORNL developed EDGAR

7 VERDE Capabilities Platform to provide wide area visualization capability Flexible system Real-time status of transmission lines Real-time weather overlays Predictive impact models & Animated replay Data analysis Energy infrastructure interdependencies: Coal delivery and rail lines Refinery and oil wells Natural gas pipelines Transportation and evacuation routes Population impacts - LandScan Streaming Analysis Wide-Area Power Grid Situational Awareness Impact Models Real-time Weather Overlays

8 Key Elements of Process Flow ICCP data from NERCnet provides real-time data every minute TVA extracts data and translates line status in or out of service ORNL overlays weather, population, transportation, electrical network data electric dynamic grid analysis Visual displays are sent to DOE every minute NERC MMWG Case PowerWorld Retriever Configuration PowerWorld Retriever Application Grid Monitoring Architecture* Phase 1: Hurricane Prone Areas ICCP Data from NERCnet TVA Extract Translate & Load Data Engine Query status of network (i.e., line flows) Weather Data Visual Display DOE HQ OE Line Mapping Data Graphical Displays 1. EDGAR JAVA Client 2. Browser to Graphic Displays 3. Google Earth Display Data Service Electrical Network Data 1. ORNL Server to EDGAR Line Status from Hurricane Prone Areas Line Status (In-service or Out-of-service) Real-time data update every 1 minute Population & Transportation Data 2. ORNL Webserver for PowerWorld Retriever Graphic Displays Visual Display DOE ESF EDGAR JAVA Client 2. Browser to Graphic Displays Utility Participants 1. EDGAR JAVA Client (TBD) & 2. Browser to Graphic Displays Electric Grid TVA Interface TVA Interface ORNL Interface EDGAR on ORNL Display Wall (EVEREST) ORNL Interface DOE/Utility Interface FEMA JFO EDGAR - Electric Dynamic Grid Analysis and Review High speed internet connection required *Contingent upon DOE obtaining access to NERC Operational Reliability Data

9 Agreements Protect Data Because the data is owned by each utility company, agreements have been executed to allow DOE access. DOE Non-Disclosure Agreement Contractor ORNL Sub-Contractor TVA Data Agreements With Participating Utilities

10 Agreement Structure to Reflect National Effort DOE Contractor ORNL Data Agreements With Participating Utilities Sub-Contractor TVA

11 Transmission Line Status Line flow in megawatts is retrieved every minute If flow is greater than 5 MW then line status is On If flow is less than 5 MW then line status is Abnormal Low power flow Actually out-of of-service Data quality flag from SCADA is also retrieved No update due to communications failure Line Status Data Quality (number of lines) Good Bad Total On, greater than 5 MW flow Abnormal, less than 5 MW flow Total
