  2. Presentation Agenda 2006 • CIM Utilization Experience • Alabama Power Specific Issues • Alabama Power Observations 2009 • Alabama / Southern AMI System (and Interface standards) • CIM Modeling Gap Analysis (for the Distribution feeder)

  3. The Southern Company Serve 4.4 Million Retail Customers Generating Capacity : 42,000 MW 120,000 Square Miles

  4. Alabama Power Company • APC serves 1,431,334 Customers • APC owns or operates 81 electric generating units with 12,222 megawatts Total Nameplate Capacity • Coal ……………… 70.53 % • Nuclear ………….. 17.99 % • Gas and Oil ……… 9.55 % • Hydro …………….. 1.93 % • Regulated by The Alabama Public Service Commission • Rate Stabilization

  5. Alabama Power Company • Install 28,000 new meters per year • Over 6,600 Employees • 10,218 Miles Transmission • 79,430 Miles Distribution • 44,500 Sq. Mile Service Territory • Six Geographic Divisions

  6. CIM Utilization Experience • Experience period – June 2006 to August 2006 • Semantic layer decouples application from data, but resulting XML file substantially increases model size • Component attributes are removed from entity causing the schema to use relationships to provide adequate attribution • Attribution is abstracted to achieve flexible data format while causing model complexity • e.g. “Address” is not an attribute of equipment, but is in the Erp.Address space

  7. CIM Utilization Experience • Graphics placement was removed from CIM • GML is used to represent graphics placement • Use of GML resulted in considerable extensions to model • Use of GML did not provide adequate means to represent the same data element as different symbols at different scales

  8. Alabama Power Specific Issues • Metering was not complete in CIM data model in 2006 • Measurement points for line-post sensors did not exist • Address information was very complex to represent using the Erp model • Distribution pole-mounted recloser was not in CIM (Breaker is included but only in the context of a substation) • Capacitor model was not complete requiring considerable number of extensions • CT’s and PT’s were not represented resulting in extension additions

  9. Alabama Power Specific Issues • Alabama model contains approximately 500 attributes • Approximately 300 attributes of the Alabama attributes were found in the CIM definitions • Approximately 100 attributes required extensions which have been added to CIM • Another approximately 100 attributes were identified as Alabama custom attributes and have not yet been added to CIM • Consequently, approximately 400 of the 500 attributes in the Alabama model are in the CIM which includes the 100 attribute extension additions

  10. Alabama Power Specific Issues • Alabama chose to use a flatter XML file specifically to manage large GIS model files to achieve: • Faster movement of smaller files across the network to support incremental updates of the operational model • Faster translation from GIS XML to IDMS XML

  11. Alabama Power Observations • Southern/Alabama supports the industry movement to a common model • For IDMS interfaces to external applications (e.g. CIS, AMI, IVR, Work Management), the vendors do not offer a CIM compliant interface • CIM is too complex and heavy for efficient movement of the GIS data model (based on the substation being the smallest increment) • Southern/Alabama will continue to pursue opportunities to use CIM messages on the utility integrated bus to externalize IDMS data to the enterprise

  12. Multi-Comm PCT/G-way Displays LCM H/W Alabama / Southern AMI System AMI Dashboard • Southern Company’s Enterprise Systems 1.5 MM Meters Proprietary Today Servers, Software & Databases (RNI) WirelessRF • CSS • Complex Billing • Load Research • EnergyDirect “Buddy Mode” IEE • Outage Management • Demand Response • Service Orders • PQView • Others Data Backhaul to SCS CIM IEC 61968-9 (IEC IS) CIM IEC 61968-8 (under development) Or Multi Speak C12.22 C12.19 C12.22 Base Station MV/XI Comm Tower Enterprise Bus FlexNet HAN SEP 2.0 MV90 PHEV Use standards Non-proprietary Interoperability EVM ION Enterprise USnap – USB Port in Home

  13. CIM Modeling Gap Analysis • CIM was originally developed to represent the transmission systems • No interoperability testing has occurred (CDPSM InterOp testing planned for November 2009) • CIM has not yet evolved to support North American distribution feeders • MultiSpeak Specification has evolved specifically to support North American feeders • Distribution Model Problem Statement • Both lines and loads are typically unbalanced • Many lines and transformers are single-phase or two-phase

  14. CIM Modeling Gap Analysis • New features are needed in CIM (specifically the CDPSM) to better support North American Distribution feeders • CIM Issues • Submitted through the IEC TC 57 / WG 14 Part 11 Modeling team • WG17? • Switching Operational Model exchange? • CIM needs Recloser and Sectionalizer classes to represent North American Distribution feeders

  15. CIM Modeling Gap Analysis • Outage Analysis Impact • Clarify the use of geographic coordinates • Bring back the EquivalentLoad class • Assign phase codes to windings • Everything outside the substation should be in a feeder container • Clarify the appearance of phases on Terminals and Connectivity Nodes

  16. CIM Modeling Gap Analysis • Power Flow testing impact • Add the full complement of control parameters for voltage regulators • For capacitor controls, add the modes for power factor, var control, time, and temperature • Add a new line code class, to facilitate transfer of power flow models • Define a structured matrix format for the phase impedance matrices of a general number of conductors and other applications

  17. CIM Modeling Gap Analysis • Asset modeling and fault analysis impact • Add a Recloser class • Add a Sectionalizer class • Add a Sensor class • Conclusions and Recommendations • Reclosers, sectionalizers, and sensors need to be added to the CIM as assets • The Distribution electrical model needs adequate representations of reclosers, sectionalizers, and sensors

  18. Presentation Epilogue 2006 • CIM Utilization Experience • Alabama Power Specific Issues • Alabama Power Observations 2009 • Alabama / Southern AMI System (and Interface standards) • CIM Modeling Gap Analysis (for the Distribution feeder)
