The study of complex dynamic processes governed by nonlinear and nonstationary characteristics is a problem of great importance in the analysis and control of power system oscillatory behavior. Power system dynamic processes are highly random, nonlinear to some extent, and intrinsically nonstationary even over short time intervals as in the case of severe transient oscillations in which switching events and control actions interact in a complex manner. Phenomena observed in power system oscillatory dynamics are diverse and complex. Measured ambient data are known to exhibit noisy, nonstationary fluctuations resulting primarily from small magnitude, random changes in load, driven by low-scale motions or nonlinear trends originating from slow control actions or changes in operating conditions. Forced oscillations resulting from major cascading events, on the other hand, may contain motions with a broad range of scales and can be highly nonlinear and time-varying. Prediction of temporal dynamics, with the ultimate application to real-time system monitoring, protection and control, remains a major research challenge due to the complexity of the driving dynamic and control processes operating on various temporal scales that can become dynamically involved. An understanding of system dynamics is critical for reliable inference of the underlying mechanisms in the observed oscillations and is needed for the development of effective wide-area measurement and control systems, and for improved operational reliability.

Picture books aren't just for little kids. They are powerful and engaging texts that can help all middle school students succeed in language arts, math, science, social studies, and the arts. Picture books appeal to students of all readiness levels, interests, and learning styles. Featuring descriptions and activities for fifty exceptional titles, Mary Jo Fresch and Peggy Harkins offer a wealth of ideas for harnessing the power of picture books to improve reading and writing in the content areas. The authors provide a synopsis of each title along with discipline-specific and cross-curricular activities that illustrate how picture books can be used to supplement--and sometimes even replace--traditional textbooks. They also offer title suggestions that create a "text set" of supporting resources. By incorporating picture books into the classroom, teachers across the disciplines can introduce new topics into their curriculum, help students develop nonfiction literacy skills, provide authentic and meaningful cultural perspectives, and help meet a wide range of learning needs.

This book proposes new control and protection schemes to improve the overall stability and security of future wide-area power systems. It focuses on the high penetration levels of renewable energy sources and distributed generation, particularly with the trend towards smart grids. The control methods discussed can improve the overall stability in normal and abnormal operation conditions, while the protection methods presented can be used to ensure the secure operation of systems under most severe contingencies. Presenting stability, security, and protection methods for power systems in one concise volume, this book takes the reader on a journey from concepts and fundamentals to the latest and future trends in each topic covered, making it an informative and intriguing read for researchers, graduate students, and practitioners alike.

This book aims to incorporate an emerging successful business model, i.e., sharing economy, into energy markets, thus digging out the potential merits and applications in multi-energy sectors. With the core idea “access over ownership”, sharing economy enables the collaborative consumption of idle resources through advanced information and communications technology. One critical challenge is to identify different market participants’ occupation while accordingly designing pricing mechanisms. This book begins with an overview about the recent development of sharing economy in energy fields, and summarizes two energy market-related issues that sharing economy can hopefully address. One is how to quantify a marginal generator’s contribution and thereby elicit truthful bidding under information asymmetry condition. The other is how to distinguish renewable and distributed energy resources’ contribution and thus incentivize efficient aggregation considering increasing scale and uncertainty. Then sharing economy mechanisms are proposed and designed from a game theory perspective. On this basis, the following chapters thoroughly investigate the specific problems in spot markets, multi-area markets, renewable energy aggregation and energy systems integration. Additionally, the benefits brought by sharing economy are evaluated in terms of regional market bidding and transmission expansion deferral. Finally, the information and communications technologies related to sharing economy are modeled and analyzed. Hopefully, this book can greatly benefit the readers who are interested in energy economics and engineering.
