The first Open Geospatial Consortium (OGC) ad hoc meeting on geospatial standards related to smart grid in the electric power utility industry was held at the OGC TC/PC meeting in Austin March 20. The turout was about 25 people representing the vendor, services, government, standards and academic communities including AIST (Japan), Autodesk, Intergraph, Oracle, GE Energy, Trimble, ESRI, Synaptitude, Northrup-Grumman, Hitachi (Japan), Secure Dimensions, Geoconnections (Canada), Canmet Energy (Canada), Geonovum (Netherlands), and universities from Belgium, the Netherlands and Japan.
There are a number of standards that are related to smart grid, some of which of which are already compliant at some level with OGC geospatial standards, such as Geography Markup Language (GML) and Web Featuure Service (WFS).
- OASIS eMIX (Energy market information exchange) used GML
- International Electrotechnical Commission (IEC) Common infirmation model (CIM) uses GML
- IEC CIM is harmonized with WXXM (Weather information exchnage model) which is based on GML
The objective of the proposed OGC domain working group (DWG) is to coordinate and develop standards to enable efficient gespatial communication within smart grids and between smart grids and neightbouring activities such as emergency response, disaster management, urban planning and building energy management. It has been proposed that the effort will be in close cooperation with ISO/TC 211 standards organization.
Related standards/activities that were mentioned include GeoBI (SAP), SGIP eMIX, IndoorGML, Canmet Energy (NRCan), NIST/SGIP, ETSI M2M, IEC 61850 (smart substations), BALLADE (smart meter networks), eMobility (EV charging stations networks), and ASHRAE.
The immediate objectives are to create a mission statement and domain working group charter to enable the group to be recongnized as an OGC Working Group (WG).
Margaret Goodrich (SISCO), who gave a presentation on extending CIM to include environmental data such as weather information (an effort sponsored by Southern California Edison), made a strong case that to attract the attention of the utility industry, developing the technical specifications for standards is not enough. Use cases and a strong business justification are essential or the standards will languish on the shelf.
