This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voltage-dependent behavior of power system load greatly influences the power system's operational characteristics, and thus appropriate load modeling is vital for accurate power system studies. The availability of fast and accurate PMU measurements at substations encourages researchers to develop aggregate load models that can be utilized in transmission voltage stability assessment. The power system's voltage stability is immensely important for secure and optimal operation and is directly impacted by load behavior. The power system's long-term voltage stability status is affected by the steady-state behavior of the power system load. It is crucial to consider the composite (dynamic + static) behavior of load for determining short-term voltage stability status. The development of accurate voltage stability assessment tools for different timing paradigms is paramount for the secure and reliable operation of the power grid.he first part of this thesis considers the development of robust load parameter estimation algorithms. This thesis develops several algorithms for accurate steady-state load parameter estimation. Firstly the regression-based load parameter estimation approaches normally considered in the literature are enhanced by leveraging more information about the numerical characteristics of PMU data. Secondly, a framework is developed to use powerful machine-learning tools for steady-state load parameter estimation. A composite load parameter estimation algorithm is developed to consider electronic load behavior in aggregate load parameter estimation. The developed load parameter estimation algorithms contribute to state of the art by improving load parameter tracking accuracy. The second part of this thesis considers the development of novel voltage stability assessment tools considering the evolving behavior of power systems. A hybrid voltage stability assessment tool is developed that appropriately considers generators' reactive power reserve status while computing the voltage stability index. Secondly, a continuation power flow tool is developed to consider the impact of the distribution system infrastructure on voltage stability status in detail. Such kind of a tool is needed to accommodate the active behavior of distribution for voltage stability assessment. Thirdly a short-term voltage stability assessment framework is developed using a 1D-convolutional neural network for early voltage collapse detection and severity quantification of short-term voltage stability events.

Download or read book Direct Methods for Stability Analysis of Electric Power Systems written by Hsiao-Dong Chiang and published by John Wiley & Sons. This book was released on 2011-03-16 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2014-07-07 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book makes the area of integration of renewable energy into the existing electricity grid accessible to engineers and researchers. This is a self-contained text which has models of power system devices and control theory necessary to understand and tune controllers in use currently. The new research in renewable energy integration is put into perspective by comparing the change in the system dynamics as compared to the traditional electricity grid. The emergence of the voltage stability problem is motivated by extensive examples. Various methods to mitigate this problem are discussed bringing out their merits clearly. As a solution to the voltage stability problem, the book covers the use of FACTS devices and basic control methods. An important contribution of this book is to introduce advanced control methods for voltage stability. It covers the application of output feedback methods with a special emphasis on how to bound modelling uncertainties and the use of robust control theory to design controllers for practical power systems. Special emphasis is given to designing controllers for FACTS devices to improve low-voltage ride-through capability of induction generators. As generally PV is connected in low voltage distribution area, this book also provides a systematic control design for the PV unit in distribution systems. The theory is amply illustrated with large IEEE Test systems with multiple generators and dynamic load. Controllers are designed using Matlab and tested using full system models in PSSE.
