Ultra-wideband (UWB) technology enables high data-rate short-range communica-
tion, in excess of hundredmegabit-per-secondsand up to multi-gigabit-per-seconds,
over a wide spectrum of frequencies, while keeping power consumption at low lev-
els. This low power operation results in a less-interfering co-existence with other
existed communication technologies (e.g., UNII bands).
In addition to carrying a huge amount of data over a distance of up to 230 feet
at very low power (less than 0.5mW), the UWB signal has the ability to penetrate
through the doors and other obstacles that tend to reflect signals at more limited
bandwidths and higher power densities.

Intensive development of digital technologies coincided in time with the beginning
of the new era in telecommunications. It made possible to formalize many proce-
dures of data exchange and to atomize some operations which made providing of
serviceandmakeworkofmanytelecommunicationworkersmucheasier. Somenew
telecommunication technologies were born out of the necessity for use of specific
configurations of network elements and networks, as well as for a possibility of
providing maximum characteristics of efficiency combined with high requirements
to the stability of operation, the overcoming of different catastrophic situations and
deadlockconditions,such as failuresand ”pending”of the networkandthe like. The
thresholdbetweeninformationsystems andtelecommunicationsystems has become
practically invisible. It resulted in such a new term as ”infocommunication”

In the seven years since the first edition of this book was completed, Electrostatic
Discharge (ESD) phenomena in integrated circuits (IC) continues to be important
as technologies shrink and the speed and size of the chips increases. The phenom-
ena related to ESD events in semiconductor devices take place outside the realm of
normal device operation. Hence, the physics governing this behavior are not typ-
ically found in general textbooks on semiconductors.

This book is written for engineers involved in the operation, control, and
planning of electric power systems. In addition, the book provides information and
tools for researchers working in the fields of power system security and stability. The
book consists of two volumes. The first volume provides traditional techniques for the
stability analysis of large scale power systems. In addition, an overview of the main
drivers and requirements for modernization of the traditional methods for online
applications are discussed. The second volume provides techniques for online security
assessment and corrective action studies. In addition, the impact of variable generation
on the security of power systems is considered in the second volume. The first volume
may be considered as a background builder while the second volume is intended for
the coverage of edge techniques and methods for online dynamic security studies.

The first edition as well as its forerunner of Kuffel and Abdullah published in
1970 and their translations into Japanese and Chinese languages have enjoyed
wide international acceptance as basic textbooks in teaching senior under-
graduate and postgraduate courses in High-Voltage Engineering. Both texts
have also been extensively used by practising engineers engaged in the design
and operation of high-voltage equipment. Over the years the authors have
received numerous comments from the text’s users with helpful suggestions
for improvements. These have been incorporated in the present edition. Major
revisions and expansion of several chapters have been made to update the
continued progress and developments in high-voltage engineering over the
past two decades.

With the proliferation of cloud computing and Internet online services, more and
more data and computation are migrated to geographical distributed Internet data
centers (IDCs), which can provide reliability, management, and cost benefits.
However, IDC operators encounter several major problems in IDC operations, such
as huge energy consumption and energy cost, and high carbon emission. To deal
with the above problems, IDC operators have to efficiently manage the way of
energy consumption and energy supply. Considering the potential of smart grid, we
focus on the energy management of IDCs in smart grid from several perspectives,
i.e., power outage, carbon emission, heterogeneous service delay guarantees, and
operation risk.

Modern day large power systems are essentially dynamic systems with stringent
requirements of high reliability for the continuous availability of electricity.
Reliability is contingent on the power system retaining stable operation during
steady-state operation and also following disturbances. The subject of power sys-
tem stability has been studied for many decades. With new developments, and there
have been many over the past couple of decades, new concerns and problems arise
that need to be studied and analysed. The objective of this book is a step in that
direction though not ignoring the conventional and well-established approaches.

The continuous progress in modern power device technology is increasingly
supported by power-specific modeling methodologies and dedicated simulation
tools. These enable the detailed analysis of operational principles on the the device
and on the system level; in particular, they allow the designer to perform trade-
off studies by investigating the operation of competing design variants in a very
early stage of the development process. Furthermore, using predictive computer
simulation makes it possible to analyze the device and system behavior not only
under regularoperatingconditions, but also at the rim of the safe-operatingarea and
beyond of it, where destructive processes occur that limit the lifetime of a power
system.

n present power system, the engineers face variety of challenges in
planning, construction and operation. In some of the problems, the engineers need
to use managerial talents. In system design or upgrading the entire system into
automatic control instead of slow response of human operator, the engineers need
to exercise more technical knowledge and experience. It is principally the engi-
neer’s ability to achieve the success in all respect and provide the reliable and
uninterrupted service to the customers. This chapter covers some important areas
of the traditional power system that helps engineers to overcome the challenges. It
emphasizes the characteristics of the various components of a power system such
as generation, transmission, distribution, protection and SCADA system. During
normal operating conditions and disturbances, the acquired knowledge will pro-
vide the engineers the ability to analyse the performance of the complex system
and execute future improvement

Modern power systems involve large amount of investment. An electric power
system comprises of generation, transmission, and distribution of electric energy.
Growth of power systems has led to very complex networks extended across large
areas. In such situations, the proper functioning of a modern power system is
heavily dependent upon the healthy operation of the transmission lines within it.
Transmission lines are used to transmit a huge amount of power over a long
distance. But as these lines are located in the open atmosphere, they are highly
affected by different types of abnormal conditions or faults.
