  • a common information model cim toolkit framework implemented in java
    2006 IEEE Power Engineering Society General Meeting, 2006
    Co-Authors: A.w. Mcmorran, I.m. Elders, G W Ault, C Morgan, J R Mcdonald
    Abstract:

    Summary form only given. The common information model (CIM) is an object-oriented representation of a power system and is used primarily as a data exchange format for power system operational control systems. CIM has the potential to be used as much more than an intermediary exchange language. This paper explores the possible use of CIM as the core of a power systems analytical toolkit for storing, processing, extracting and exchanging data directly from CIM objects. To this end, the paper discusses solutions to some of the challenges in storing and processing large power system network models as native Java objects without sacrificing reliability and robustness. The paper highlights the advantages provided by such a system when dealing with extensions to the CIM standard and overcoming the problems posed with simultaneously maintaining backwards compatibility without sacrificing a higher level of detail. The paper also addresses the issue of data processing performance in contrast to other approaches.

  • translating cim xml power system data to a proprietary format for system simulation
    IEEE Transactions on Power Systems, 2004
    Co-Authors: A.w. Mcmorran, I.m. Elders, C.e.t. Foote, Graeme Burt, G W Ault, James R. Mcdonald
    Abstract:

    The problem of exchanging data between two or more organizations in a format that is accessible and understandable by each is a universal problem. Furthermore, the problem of translating or accessing data in the correct format for applications using proprietary data formats is challenging. Legacy software applications may endure, for some time given, regulatory expenditure pressures on electricity system operators and these require data translators (importer/exporter) and access facilities. The basis of this paper is that the Electric Power Research Institute (EPRI) common information model (CIM) in eXtensible Markup Language (XML) represents the first stage in a revolution of data exchange and manipulation for power systems. This paper explores the problem of translating data in the CIM XML format to the required format for such legacy power system analysis applications. This paper discusses solutions to some of the challenges in data translation, and illustrates how these solutions can be implemented.

  • Smart Grid Interoperability Use Cases for Extending Electricity Storage modeling within the IEC common information model
    2014
    Co-Authors: Nigel Hargreaves, Gareth Taylor, Alex Carter
    Abstract:

    recognized as a core standard, supporting electricity transmission system interoperability. Packages of UML classes make up its domain ontology to enable a standardised abstraction of network topology and proprietary power system models. Since the early days of its design, the CIM has grown to reflect the widening scope and detail of utility information use cases as the desire to interoperate between a greater number of systems has increased. The cyber-physical nature of the smart grid places even greater demand upon the CIM to model future scenarios for power system operation and management that are starting to arise. Recent developments of modern electricity networks have begun to implement electricity storage (ES) technologies to provide ancillary balancing services, useful to grid integration of large-scale renewable energy systems. In response to this we investigate modeling of grid-scale electricity storage, by drawing on information use cases for future smart grid operational scenarios at National Grid, the GB Transmission System Operator. We find current structures within the CIM do not accommodate the informational requirements associated with novel ES systems and propose extensions to address this requirement

  • foundations of a metamodel repository for use with the iec common information model
    IEEE Transactions on Power Systems, 2013
    Co-Authors: Nigel Hargreaves, A M Carter, Stefan Pantea, G A Taylor
    Abstract:

    The development of the smart grid calls for enhanced power system application interoperability and knowledge management. The IEC common information model (CIM) supports semantic interoperability but multiple identities attributed to common power system resources present challenges to unambiguous metadata model merging within a repository. This paper describes an original methodology for the building of a novel metadata model repository that concentrates our knowledge of enterprise power system resources. We leverage the value of model namespaces and resource description framework (RDF) technology in providing contexts for multiple identities referring to common power system resources. This novel approach aims to develop a more realistic understanding of network reality than repositories depending on a single CIM XML namespace and contributes to engineering an “enterprise ontology” supporting interoperability and business intelligence. We demonstrate this novel approach with reference to National Grid use cases for network operation and planning model management roles.
