Real-Time Stability in Power Systems by Savu C. Savulescu Pdf

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 by Mania Pavella,Damien Ernst,Daniel Ruiz-Vega Pdf

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).

Advancements in Real-Time Simulation of Power and Energy Systems by Panos Kotsampopoulos,Md Omar Faruque Pdf

Modern power and energy systems are characterized by the wide integration of distributed generation, storage and electric vehicles, adoption of ICT solutions, and interconnection of different energy carriers and consumer engagement, posing new challenges and creating new opportunities. Advanced testing and validation methods are needed to efficiently validate power equipment and controls in the contemporary complex environment and support the transition to a cleaner and sustainable energy system. Real-time hardware-in-the-loop (HIL) simulation has proven to be an effective method for validating and de-risking power system equipment in highly realistic, flexible, and repeatable conditions. Controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) are the two main HIL simulation methods used in industry and academia that contribute to system-level testing enhancement by exploiting the flexibility of digital simulations in testing actual controllers and power equipment. This book addresses recent advances in real-time HIL simulation in several domains (also in new and promising areas), including technique improvements to promote its wider use. It is composed of 14 papers dealing with advances in HIL testing of power electronic converters, power system protection, modeling for real-time digital simulation, co-simulation, geographically distributed HIL, and multiphysics HIL, among other topics.

Intelligent Systems for Stability Assessment and Control of Smart Power Grids by Yan Xu,Yuchen Zhang,Zhao Yang Dong,Rui Zhang Pdf

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.
