Smart grid interoperability use cases for extending electricity storage modeling within the IEC Common Information Model

Abstract

Abstract-The IEC Common Information Model (CIM) is 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.Index Terms-Common Information Model, CIM, interoperability, smart grid, energy storage.

A Comprehensive Review of Practical Issues for Interoperability Using the Common Information Model in Smart Grids

“…Energy storage devices can increase the availability of renewable resources by providing ancillary balancing services for the uncertainty of renewable resources. Hargreaves et al [49] classified the energy storage devices that can be connected to power systems through energy storage methods. In addition, the paper defined the energy storage unit as a refinement of the RegulatingCondEq class.…”
