First Edition

System Integrity Protection Schemes (SIPS) are one of the main components at the top level of the protection and control hierarchy. They have been implemented for many years typically based on dynamic stability analysis of the impact of system events on the security of the electric power system.

Synchrophasor measurements can bring SIPS to a different level by allowing them to better observe the dynamic state of the electric power system and adapt their behavior when a system event occurs. This can be accomplished using Wide Area Monitoring, Protection and Control systems.

The title of the book is exactly that, with the addition of “The Gateway to Smart Grids.” It is a relatively small book - about 150 pages, published in paperback by Lambert Academic Publishing.

The authors of the book come from industrial and academic background, which allows them to write about the subject with a more practical point of view, while at the same time introducing some more theoretical methods in a real project.

The first chapter of the book is a short introduction of the development and possible impact of synchrophasor measurements on wide area monitoring and protection. It also includes an overview of the research, development and application of phasor and wide area technologies in different countries around the world.

Chapter two concentrates on wide area systems components and architectures, including some discussion on the importance of the Global Positioning System (GPS), Phasor Measurement Units (PMU) and Phasor Data Concentrators (PDC) as key components of these systems. Remedial Action Schemes (RAS) are briefly introduced together with communications architectures and some analysis on the factors that may have an impact on the performance of the system.

Chapter three proposes a WAMPAC system that includes remedial actions to mitigate power system instabilities. A review of methods for transient instabilities detection is followed by an Artificial Neural Networks (ANN) based method proposed for instability prediction. Controlled islanding and load-shedding strategies are described briefly at the end of this chapter.

Chapter four demonstrates the results from the simulation of the proposed WAMPAC system on the New England IEEE 39 bus system using PSAF and MATLAB. The ANN based transient instability predictor is also evaluated.

In the last chapter of the book the ideas presented earlier are applied to the Egyptian power system. A new idea in this chapter is the use of Bioinformatics techniques for identification of coherent groups of generators.

One thing that is missing from the book is a description of the relationship between WAMPAC and the Smart Grid. Even that the title of the book states that it is a gateway to the smart grids, there is nothing in the book addressing this issue.
