Making Smart Grid Real
(Computer Communications and Networks)

The electric power industry is in a period of transition from the hardwired grid of the last century towards the computers and communications based Smart Grid of the 21st century. However, many utilities do not have the communication networks that are required for the implementation of Smart Grid technologies.
The application-centric approach of the book is based on the fact that all authors have advanced degrees, have performed research and been involved in development and deployment of communication networks as members of the Alcatel-Lucent’s team.

The more than 350 pages of material is organized in twelve chapters and four appendixes. To define the requirements for the communication networks, the first chapter is an introduction to the concept and characteristics of Smart Grids. This is followed by a chapter that introduces some basics about electric power systems for communications specialists that are new to our industry.
Chapter 3 is the opposite to the previous - it is an introduction of topics in communication networks for electric power systems specialists, including many wireless and wired technologies. Since IP will be one of the network protocols of choice for the evolving smart networks, relevant IP networking features are described in more detail, together with the Multiprotocol Label Switching (MPLS) technology which provides many important features needed in the Smart Grid.

The next two chapters discuss conventional applications in utility operations and the differences in Smart Grid applications.
Chapter 6 is focused on the Smart Grid core-edge communication network architecture, including the concept of the wide area network (WAN) and field area networks (FANs) in the utilities.
Chapter 7 is an overview of Smart Grid network design process and is based on the characterization of Smart Grid logical connectivity and network traffic that are the inputs to network design in order to support the definition of the requirements on routing, quality of service (QoS), and network reliability.

It briefly touches on security, but this topic is the main focus of Chapter 8. Network security is one of the main requirements for Smart Grid communication networks and the authors conclude that cybersecurity of the power grid has become as important as physical security.
Chapter 9 provides an overview of communication network technologies appropriate for WANs and the FANs. For WAN, optical networks are discussed in detail, including fiber infrastructure with optical ground wire (OPGW).
Both wired and wireless networking technologies are considered with special emphasis of their use as FANs.
Smart Grid data management is discussed in Chap. 10 in the context of data collection, storage, and access across the communication network, while Chapter 11 brings together the concepts, technologies, and practices in the realization of communication networks for the Smart Grid. In this chapter the focus is on the transformation from the present mode of utility operation over multiple separate networks - to an integrated network based on the Smart Grid architecture framework presented in this book.

The last chapter of the book includes some ideas and discussions about the future of Smart Grid communications.
In summary, this book is a very well written resource that can help many PAC specialists in expanding their knowledge about communication networks as part of the transition towards the Smart Grid.
