“…The CIM provides an object-oriented, scalable and extensible semantic model for modeling power system resources. IEC61970 was originally intended as a common information model to map energy management system application programming interfaces (EMS-API) for transmission system operation but has grown to become a power utility domain ontology [4]. Successive releases of the CIM, driven by power utility information use cases, are continuously increasing its scope and resolution to support smart grid scenarios for power system interoperability and management [5].…”

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.

“…Due to the differences in the way application vendors have modeled the real network, these interfaces have often required custom development to suit individual power utility needs. With the emergence of smart grids the need for power system interoperability is seen as an essential component of the required flexibility to manage increasingly dynamic supply and demand scenarios [1]. Sharing of data between heterogeneous power systems and other applications forms the basis of control system This work is funded and supported by National Grid Plc and the Engineering and Physical Sciences Research Council (EPSRC) for funding this research project.…”

Abstract--Electricity network resources are frequently identified within different power systems by inhomogeneous names and identities due to the legacy of their administration by different utility business domains. The IEC 61970 Common Information Model (CIM) enables network modeling to reflect the reality of multiple names for unique network resources. However this issue presents a serious challenge to the integrity of a shared CIM repository that has the task of maintaining a resource manifest, linking network resources to master identities, when unique network resources may have multiple names and identities derived from different power system models and other power system applications. The current approach, using CIM 15, is to manage multiple resource names within a singular CIM namespace utilizing the CIM "IdentifiedObject" and "Name" classes. We compare this approach to one using additional namespaces relating to different power systems, similar to the practice used in CIM extensions, in order to more clearly identify the genealogy of a network resource, provide faster model import times and a simpler means of supporting the relationship between multiple resource names and identities and a master resource identity.

SOUSA, Jeovane Vicente de. Cloud Computing in the Smart Grids context: An Application to Aid Fault Location in Distribution Systems. 183 p. Ph.D. Thesis -São Carlos School of Engineering, University of São Paulo, São Carlos, 2018. Cloud computing has been envisioned as the main technology capable to integrate and manage many systems on a Smart Grid. Thus, this research aims to develop a cloud computing infrastructure to store and manipulate smart distribution system data. By analyzing the infrastructure of the main applications using cloud computing for smart distribution systems, an extensible architecture with essential services was proposed to host smart distribution systems services and applications. Based on this proposition, a cloud computing platform was developed using open source tools. A new application to reduce multiple estimation for fault location in radial distribution systems using datamining techniques over smart meter data was implemented using this infrastructure. An optimized version of the datamining tool known as DAMICORE (Data Mining of Code Repositories) was implemented as an extension to the proposed architecture basic services. The new cloud application was tested using hundreds of fault simulations through a test feeder, being able to reduce the line extensions with multiple estimation by more than 80% in the simulated fault cases. The results show that the proposed cloud computing architecture and infrastructure enable new smart distribution systems applications, contributing to the development of smart grids and diffusion of cloud computing in this context. As an additional contribution, the cloud application developed will help to reduce the multiple estimation for fault locations in distribution systems.
