IntelliGrid Common Information Model Primer: Second Edition

The Common Information Model (CIM) Primer explains the basics of the CIM (IEC 61970, IEC 61968, and IEC 62325). Starting with a historical perspective, it describes how the CIM originated and grew through the years. The functions of various working groups of Technical Committee 57 of the International Electrotechnical Commission (IEC) are described. The process of how an IEC standard is created is also outlined.
The basics of the Unified Modeling Language (UML) are detailed to introduce the reader to the language of the CIM. Then, building on commonly understood objects (basic shapes), the concepts that underline the CIM are carefully built step by step. The reader is then transported into the world of power systems where the concepts that were developed previously are applied to the complexities of the electric grid.
The Second Edition is updated with a case study that follows a utility through its journey of discovery, learning, and then, utilizing the CIM for grid modeling and integration. Additionally, questions have been added to the end of each section for the reader to reinforce their learning.
