This book was released on 2013 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis proposes a novel transform called "Channel Components Transform" and presents its application to power system voltage stability assessment. The transform is based on the following observation: a power network can be represented as a multi-node, multi-branch Thevenin circuit connecting the loads to the generators. If one applies eigen-decomposition on the Thevenin impedance matrix, the network can be decoupled into a set of single-branch equivalent circuits. These circuits are much easier to analyze and they carry valuable information of a power system. Similarly, if the variations of the transformed variables can be evaluated, one may be able to predict the complex behaviours of the actual network. The eigen-decomposition of the Thevenin impedance matrix and associated operations are named "Channel Components Transform" (CCT). The thesis shows that CCT can establish a framework to assess the voltage stability conditions of a power system. Techniques are developed to identify the critical modes (called channels) involved in voltage collapse, the associated critical buses, generators, and branches. These methods are tested using various test systems including an actual large power system. The results confirm that the developed methods are useful tools for assessing the voltage stability of a complex power system. A wide-area scheme for the online voltage stability monitoring based on the proposed CCT-based framework is proposed. A methodology for optimal placement of Phsor Measurement Units (PMUs) is also proposed in order to minimize the number of required PMUs and as a result, make the implementation procedure practical. A CCT-based algorithm to facilitate the planning of reactive power support is developed. Using the proposed algorithm, the optimal location and amount of reactive supports are determined in order to increase the voltage stability margin. The application of Singular Value Decomposition (SVD) in the proposed CCT is also investigated in this thesis.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops a pioneering methodology and a concept for identifying critical loads and load model parameters in large power networks based on their influence on power system stability. The research described in the thesis first develops an automatic load modelling tool (ALMT) that can be used to automatically build load model from actual measured power system data without human intervention and the benefits of the ALMY are explored. Secondly, it develops a pioneering framework based on Morris screening method for ranking power system load model parameters based on their influence on overall power system stability (voltage, frequency, transient and small disturbance stability) considering different load models and loading conditions. Thirdly, a novel probabilistic methodology for determining the accuracy levels of critical load model parameters has been developed. This book will be of interest to students and researchers within the field of electrical engineering, as well as industry professionals.

Download or read book Intelligent Systems for Stability Assessment and Control of Smart Power Grids written by Yan Xu and published by CRC Press. This book was released on 2020-12-10 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power systems are evolving towards the Smart Grid paradigm, featured by large-scale integration of renewable energy resources, e.g. wind and solar power, deeper participation of demand side, and enhanced interaction with electric vehicles. While these emerging elements are inherently stochastic in nature, they are creating a challenge to the system’s stability and its control. In this context, conventional analysis tools are becoming less effective, and necessitate the use alternative tools that are able to deal with the high uncertainty and variability in the smart grid. Smart Grid initiatives have facilitated wide-spread deployment of advanced sensing and communication infrastructure, e.g. phasor measurement units at grid level and smart meters at household level, which collect tremendous amount of data in various time and space scales. How to fully utilize the data and extract useful knowledge from them, is of great importance and value to support the advanced stability assessment and control of the smart grid. The intelligent system strategy has been identified as an effective approach to meet the above needs. This book presents the cutting-edge intelligent system techniques and their applications for stability assessment and control of power systems. The major topics covered in this book are: Intelligent system design and algorithms for on-line stability assessment, which aims to use steady-state operating variables to achieve fast stability assessment for credible contingencies. Intelligent system design and algorithms for preventive stability control, which aims at transparent and interpretable decision-making on preventive control actions to manipulate system operating condition against possible contingencies. Intelligent system design and algorithms for real-time stability prediction, which aims to use synchronized measurements to foresee the stability status under an ongoing disturbance. Intelligent system design and algorithms for emergency stability control, which aims at fast decision-making on stability control actions at emergency stage where instability is propagating. Methodologies and algorithms for improving the robustness of intelligent systems against missing-data issues. This book is a reference and guide for researchers, students, and engineers who seek to study and design intelligent systems to resolve stability assessment and control problems in the smart grid age.

This book was released on 2009-03-04 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book answers the need for a practical, hands-on guide for assessing power stability in real time, rather than in offline simulations. Since the book is primarily geared toward the practical aspects of the subject, theoretical background is reduced to the strictest minimum. For the benefit of readers who may not be quite familiar with the underlying theoretical techniques, appendices describing key algorithms and theoretical issues are included at the end of the book. It is an excellent source for researchers, professionals, and advanced undergraduate and graduate students.

This book was released on 2020-01-27 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with two important and very timely aspects of the future power system operation - assessment of demand flexibility and advanced demand side management (DSM) facilitating flexible and secure operation of the power network. It provides a clear and comprehensive literature review in these two areas and states precisely the original contributions of the research. The book first demonstrates the benefits of data mining for a reliable assessment of demand flexibility and its composition even with very limited observability of the end-users.
