This book reviews and examines how power system low-frequency power
oscillations and sub-synchronous oscillations may be affected by
grid connection of wind power generation. Grid connection of wind
power generation affects the power system small-signal stability
and has been one of the most actively pursued research subjects in
power systems and power electronics engineering in the last ten
years. This book is the first of its kind to cover the impact of
wind power generation on power system low-frequency oscillations
and sub-synchronous oscillations. It begins with a comprehensive
overview of the subject and progresses to modeling of power systems
and introduces the application of conventional methods, including
damping torque analysis, modal analysis and frequency-domain
analysis, presented with detailed examples, making it useful for
researchers and engineers worldwide.

This book presents the research and development results on power
systems oscillations in three categories of analytical methods.
First is damping torque analysis which was proposed in 1960's,
further developed between 1980-1990, and widely used in industry.
Second is modal analysis which developed between the 1980's and
1990's as the most powerful method. Finally the linearized
equal-area criterion analysis that is proposed and developed
recently. The book covers three main types of controllers: Power
System Stabilizer (PSS), FACTS (Flexible AC Transmission Systems)
stabilizer, and ESS (Energy Storage Systems) stabilizer. The book
provides a systematic and detailed introduction on the subject as
the reference for industry applications and academic research.
This book develops a modeling framework to analyze the problem of
inventory management with alternative delivery times. The general
context considered here is that a seller replenishes its inventory
in fixed intervals and, between replenishments, allocates the
limited inventory to satisfy customers who are both price and
delivery-time sensitive. On the demand side, customers have
heterogeneous delivery-time requirements and choose either spot or
late delivery. This theoretical modeling captures the essence of
real-world business practices such as the delivery time market
segmentation strategy adopted by automobile dealerships in China
and many other similar examples. The book focuses on the seller's
optimal inventory replenishment and demand fulfillment policies,
and our results provide managerial insights into the merits of
flexible delivery-time options. Similar applications such as the
group-buying mechanism are also examined. The main mathematical
tool used in theoretical analysis is dynamic programming. This book
is written for students, researchers, and practitioners in the
areas of operations management and industrial engineering who are
interested in understanding the rationale of flexible delivery
times and designing successful applications.

This book constitutes the refereed proceedings of the 12th China
National Conference on Computational Linguistics, CCL 2013, and of
the First International Symposium on Natural Language Processing
Based on Naturally Annotated Big Data, NLP-NABD 2013, held in
Suzhou, China, in October 2013. The 32 papers presented were
carefully reviewed and selected from 252 submissions. The papers
are organized in topical sections on word segmentation; open-domain
question answering; discourse, coreference and pragmatics;
statistical and machine learning methods in NLP; semantics; text
mining, open-domain information extraction and machine reading of
the Web; sentiment analysis, opinion mining and text
classification; lexical semantics and ontologies; language
resources and annotation; machine translation; speech recognition
and synthesis; tagging and chunking; and large-scale knowledge
acquisition and reasoning.
This book provides a systematic introduction to power system
sub/super-synchronous oscillations caused by grid-connected wind
power generation. The authors look at why oscillations occur and
present methods for examining the risk of oscillations. Coverage
includes state-space model based analysis and impedance model based
analysis, which are the two main methods for examining the power
system sub/super-synchronous oscillations. In addition, new methods
for examining oscillations in wind farms are proposed.Â
Analysis of Power System Sub/Super-Synchronous Oscillations Caused
by Grid-connected Wind Power Generation provides researchers and
students with a single-volume introduction to the subject and will
be a valuable professional reference for practicing engineers
looking for solutions to oscillation problems.

systems oscillations in three categories of analytical methods.
