Abstract

With the advent of smart grid, the grid needs to be smarter and needs to move operation of distribution networks toward more active management manner. Successful applications for smart grid require an enterprise level system perspective which views generations and loads as an integrated and autonomous subsystem. The smart grid is a complex network system that must operate in diverse and often challenging environments that combine very large complex facilities with vast number of intelligent devices such as smart meters. To support these needs, many sophisticated software tools are used for interoperating. Utility companies responsible for secure power system operation need to model their systems and part of systems in support of control, security and economics functions actively. To do this, they need to exchange system modeling information with one another. Unfortunately, the existing model exchange formats derive from planning models that are bus/branch oriented and lack details required for control center operations. The information needed for real-time power system operation requires far greater detail about field equipment and its connectivity. These models, referred to as a node/breaker model, must include the substation bus segments, breakers, and measurement details. Recently, the Common Information Model (CIM) has been established as a common language and domain model. The CIM can be used to share and exchange information models among different applications across operations and planning platforms in utility companies. The CIM can save time spent on developing adapters which can be used to improve the applications.

This tutorial discusses the CIM and its benefits on a current power system analysis tools as CIM trend will become standard in many power system analysis tools. Examples using CIM are shown for energy management systems (EMS) interface, loadflow interface, transient stability interface and advanced model integration.

Objectives

• To introduce the concept of using CIM to Smart Grid applications
• To provide the solutions in the established practice of power system data sharing and exchange which are required for future Smart Grid applications.
• To demonstrate some real examples of using CIM to enhance the capability of existing power system analysis software.

Target Audience

The tutorial is designed for general audience who is new to the area of Common Information Model (CIM). Experiences in Smart Grid design in general and basic knowledge in power system analysis and modeling in particular, is preferable, but not necessary. Participants with background in power system modeling, power system application design will be able to apply readily what they learn in comparison to their own experiences, which is always beneficial.
