Book Description
Learn how to implement BCU methods for fast direct stability assessments of electric power systems Electric power providers around the world rely on stability analysis programs to help ensure uninterrupted service to their customers. These programs are typically based on step-by-step numerical integrations of power system stability models to simulate system dynamic behaviors. Unfortunately, this offline practice is inadequate to deal with current operating environments. For years, direct methods have held the promise of providing real-time stability assessments; however, these methods have presented several challenges and limitations. This book addresses these challenges and limitations with the BCU methods developed by author Hsiao-Dong Chiang. To date, BCU methods have been adopted by twelve major utility companies in Asia and North America. In addition, BCU methods are the only direct methods adopted by the Electric Power Research Institute in its latest version of DIRECT 4.0. Everything you need to take full advantage of BCU methods is provided, including: Theoretical foundations of direct methods Theoretical foundations of energy functions BCU methods and their theoretical foundations Group-based BCU method and its applications Numerical studies on industrial models and data Armed with a solid foundation in the underlying theory of direct methods, energy functions, and BCU methods, you'll discover how to efficiently solve complex practical problems in stability analysis. Most chapters begin with an introduction and end with concluding remarks, making it easy for you to implement these tested and proven methods that will help you avoid costly and dangerous power outages.

Real-Time Stability in Power Systems

Real-Time Stability in Power Systems PDF Author: Savu C. Savulescu
Publisher: Springer Science & Business Media
ISBN: 9780387256269
Category : Technology & Engineering
Languages : en
Pages : 360

Book Description
In the aftermath of the wave of blackouts that affected US, UK and mainland Europe utilities in 2003 and 2004, renewed attention has been focused on maintaining the highest level of reliability and security in the operation of power systems. The lack of adequate transmission infrastructure as well as real-time tools aimed at detecting and alarming system conditions have also been highlighted. In this context, the need to assess stability and predict the risk of blackout in real-time has become particularly relevant. Early work in this field documented in technical papers published throughout the 1990s and early 2000s underlined the importance of performing stability assessment in real-time. While static security assessment is conceptually straightforward, innovative approaches are needed to combine it with dynamic security assessment to develop an overall scheme so that results can be used for on-line decision-making. On October 13, 2004, the IEEE Power Systems Conference and Exposition 2004 hosted the ‘Real-Time Stability Challenge’ panel session. Organized by the Power System Dynamic Performance Committee, the panel was a forum for presenting progress achieved in this field, discussing new ideas, and identifying the challenges to be met in the course of future research. Real-Time Stability in Power Systems: Techniques for Early Detection of the Risk of Blackout is built around most of the panel papers, updated and expanded by the authors with the new material relevant to the panel theme. The chapters are contributed by well known experts in the field, thus providing an authoritative reference on the theory and implementation of real-time stability assessment -- one of the critical topics of the day. Some of the issues discussed in the book include, but are not limited to: *Stability limits and how to objectively define them, *Techniques for defining and measuring the distance to instability, *The characterization of the risk of blackout, *Discussion of quick, approximate methods to filter out non-critical contingencies and do a detailed simulation only of those that result in limit violations, *Theoretical description and practical experience with real-time and/or near real-time stability applications available today in the SCADA/EMS industry.

Transient Stability of Power Systems

Transient Stability of Power Systems PDF Author: Mania Pavella

Languages : en
Pages : 251

Book Description
The market liberalization is expected to affect drastically the operation of power systems, which under economical pressure and increasing amount of transactions are being operated much closer to their limits than previously. These changes put the system operators faced with rather different and much more problematic scenarios than in the past. They have now to calculate available transfer capabilities and manage congestion problems in a near on line environment, while operating the transmission system under extremely stressed conditions. This requires highly reliable and efficient software aids, which today are non-existent, or not yet in use. One of the most problematic issues, very much needed but not yet en countered today, is on-line dynamic security assessment and control, enabling the power system to withstand unexpected contingencies without experienc ing voltage or transient instabilities. This monograph is devoted to a unified approach to transient stability assessment and control, called SIngle Machine Equivalent (S1ME).

Computational Methods for Electric Power Systems

Computational Methods for Electric Power Systems PDF Author: Mariesa L. Crow
Publisher: CRC Press
ISBN: 9780849313523
Category : Technology & Engineering
Languages : en
Pages : 264

Book Description
The sheer size of today's power grid and the increasingly stressed conditions under which power systems operate demand the use of computers for analysis and simulations. Yet commercial software packages often fail or give erroneous results when used to simulate stressed systems. To correctly interpret the results, it is therefore imperative that power engineers understand the underlying numerical algorithms of the software. Computational Methods for Electric Power Systems provides a comprehensive study of the various computational methods that form the basis of many analytical studies of power systems. It presents the analytical background of the algorithms used in many commercially available software packages, thereby enabling readers to make more informed decisions in their use of the software and correctly interpret their results. The book furnishes a well-balanced discussion of the theory and applications of the algorithms and supports them with instructional examples and illustrations. As more and more demands are placed on the nation's power systems, predicting and updating the operating status of a network through systems analysis becomes increasingly important. This book builds the background necessary to successfully perform that analysis and prepares readers to cope with any difficulties they may encounter in practice.
