1 CIMPHONY Alan McMorran Open Grid Systems

2 History Cimphony was the product of a number of initiatives for dealing with power system data Started in 2002, built from there in an evolutionary manner Used a number of custom frameworks Web-based written in Java, run under Apache-Tomcat Used at a number of Interoperability tests for validation of model instances 2

3 Open Grid Systems Left the University in March 2010, formed Open Grid Systems Ltd. Cimphony has proved itself very useful, but the technology stacks available today are superior and more mature Complete re-write of Cimphony code to run under OSGi with Eclipse-based UI and to use standards in place of custom frameworks Common components for server, CLI and UI interfaces 3

4 OSGi OSGi is a module and service system for Java Supports dynamic component loading Eclipse is built on an OSGi runtime OSGi runtimes can be used to deploy web services, run rich client applications, command line utilities or server based solutions Cimphony is now built as OSGi bundles Bundles provide functionality, services and extensions 4

5 Eclipse Modelling Framework Cimphony previously used a custom Java generation library for producing objects from a meta-model A CIMTool extension now produces Ecore models from any meta-model loaded into CIMTool (or from a profile) Ecore is the meta-model language for the Eclipse Modelling Framework (EMF) Adding new meta-models to Cimphony is now done using EMF tools built into Eclipse 5

7 Structure vs Format This approach separates the structure of data from its format using ResourceImpl to serialise/deserialise data RDF XML becomes just one serialisation mechanism, the software deals with data as objects (know as EObjects for EMF Ecore DataModel Serialised Data ResourceImpl ResourceImpl Serialised Data EObjects 7

8 Cimphony Frameworks RDF - Meta-model agnostic RDF XML interface Profiles - Support for profiles and groups for profiled import and export of data as multiple datasets Validation - OCL based validation framework with registry for registering multiple validation profiles Transformation - QVTO based transformation framework for registering and running transformations on data Web Services - Support for exposing functionality using Web Services 8

VoltageAngle; TopologicalNode := result; }; } 10

11 Cimphony Frameworks Topological Processing - for creating bus-branch network representations. Registers multiple processors for different schemas Geographical Tools - tools for geographical visualisation including coordinate conversion, KML generation, heatmap overlays for voltage dips or line ratings ZCIM - native support for dealing with multiple datasets within a single Zip archive 11

16 Cimphony Frameworks Multiple schemas already supported CIM v10-15 ERCOT Nodel Market model Multispeak v3 IEC61850 SCL PSS/E v31 & 32 Google Earth KML v2.1 16

17 Validation Profiles ENTSO-E 2010 Equipment, Topology, State & Dynamics Auto-generated from OWL then added extended restrictions OCL profile CPSM 2010 Equipment, State As with ENTSO-E, added extended restrictions CDPSM

18 User Interface Work until now has focussed on the functionality and frameworks A good UI though is needed for useful desktop applications Meta-model agnostic Graphical tree-editor and browser built on open-source Eclipse EMF Editor can be used to browse data sets Single Line Diagram Editor for viewing, creating and editing single line diagrams (with support for multiple different meta-models inc. CIM14 and PSS/E) 18

20 Cimphony Applications A CIM Validator was released on 16/6/2010 for Interoperability participants Uses core Cimphony frameworks with CIM 14v15 meta-model and validation profiles for CPSM and ENTSO-E Command-line app using OSGi runtime, engine is model and profile agnostic Needed to be produced quickly (within a few days) hence the lack of a UI! 20

23 Plans For interoperability tests: SLD Editor and Hierarchical browser Integrated load-flow and state-estimation engine CIM Incremental support (Import/Export) Beyond: Database-driven model persistence using Connected Data Objects (CDO) framework Support for additional schemas, formats, transformations, validation profiles etc. Full UI for transformation, validation and analysis 23

24 Extensible The majority of frameworks and tools are all model agnostic Wide use of service registries to enable dynamic deployment of meta-models, profiles, transforms etc. Already been extended to support additional models (e.g. PSS/E) and extended CIM model (ERCOT) Uses open-source Eclipse/OSGi based tools and libraries The frameworks will be released under LGPL and EPL licenses 24
