Real-Time Stability Assessment in Modern Power System Contro

The book begins with a SCADA/EMS primer aimed at familiarizing the reader with the real-time and study mode data environments in modern control centers. These installations became quite sophisticated and offer superb application integration opportunities that were not available just a few years ago. This background is complemented with a brief review of the stability landscape from the real-time implementation perspective. The subsequent material is clustered along the lines traditionally recognized in the industry from steady-state stability, to transient stability, and to voltage stability. Within these clusters, each chapter describes actual solutions, emphasizes the particular challenges that were faced, shows how the problems were solved, and shades light on the experimental results. The next group of chapters addresses transient stability.Among other things, itdescribes the implementation of on-line Transient Security Assessment at Southern Company Services by Powertech Labs (Powertech) and provides details about the simulation model, including the dynamic equivalent of the external system, and the complex hardware architecture that supports the computations. Because the book aims primarily at the practical aspects of implementing stability assessment in real-time, the space for theoretical background in each chapter was reduced to the strictest minimum. For the benefit of readers who may not be quite familiar with the underlying theoretical techniques, appendices that describe the key algorithms and discuss some theoretical issues directly related to the subject matter of the book are included at the end.
