use of polymeric insulators, and procedures for selecting insulators for ac and dc
transmission lines are also discussed.
Chapters 11 and 12 deal with the
design considerations for the insulation
structures used in hV underground
cables and power transformers. Chapter 11 covers the electrical performance
and design considerations for underground cables using oil-paper insulation, extruded insulation, and compressed gas insulation. A discussion of
gas-insulated substations is included.
design considerations for oil-paper insulation structures used in transformer
windings are described in Chapter 12.
insulation coordination is an important consideration in the design of
hV power equipment and systems. The
procedure for insulation coordination is
explained in Chapter 13, including both
the methods of deterministic withstand
voltage and the statistical approach
based on risk of failure.
Testing and measurement techniques,
traditionally considered the essence of
hV engineering, are covered in detail
in Chapter 14. The generation of ac test
voltages with cascade transformers and
resonant circuits, dc test voltages with
cascade rectifiers, and impulse voltages
with multistage generators is described
in this chapter. it also describes the use
of cascade transformers for generating
switching surge voltages and accuracy
requirements for voltage measurements
using different types of voltage dividers.

evidence needed to dispel that notion is a
quick flick through the contents pages of
Renewable Energy Integration: Practical Management of Variability, Uncertainty, and Flexibility in Power Grids,
edited by Lawrence e. Jones. renewables
are taking their place as
a mainstream pillar of
the energy network that
underpins society with
the speed of Moore's
law. That transition is far
from localized to certain
countries: this is a global
phenomenon. This book
makes a point of this by
illustrating the global
scale of the transition
by drawing on insightful input from a cadre of luminaries in the
industry, spanning six continents.
in an environment as fluid as we
find ourselves in, good information is
key. That global scale of the energy
transition means that almost every aspect of power system planning and operation has or will be affected in some
way. stakeholders have been dealing
with the challenges arising from the
transition as they present themselves in
each system, generating considerable
knowledge and a smorgasbord of solutions that this book has tried to capture.
The previously black-and-white delineation between a planning task and
the operation of the power system has
gone Technicolor. while planners and
operators must reassess the suitability
of their processes in their own silos, it is
utterly necessary to understand how the
other is impacted by this transition -we
need jacks of all trades and masters of
some. it is precisely this need that would
motivate a reader to pick up a copy of
Renewable Energy Integration. This
book's intent is to create a reference to
cover the essential aspects of a wide
range of topics in a way that is accessible
and provides good quality references to
additional works for those whose thirst
for information is not satiated.
The book is split into ten parts and 35
chapters covering topics ranging from
policy relating to renewables all the
way through to situational awareness in

the control room. whereas other books
in this arena can focus singularly on a
specific technology, this book places the
transition to renewables into the overall
systemwide context. As a result, some of
the topics covered are not just beneficial
to areas experiencing
growth in wind and solar generation but as an
overview in the state of
the art of techniques to
manage variability and
uncertainty, today and in
the future.
The earlier chapters of
the book are devoted to the
policy driving the energy
transition, with notable
emphasis on experience
in europe, the United states, Africa, and
india. issues such as market integration are
examined in the context of growing renewable generation. The book illustrates how
markets are evolving to become more adept
at integrating renewables through new ancillary services and the adaption of existing
market rules.
The uncertain aspect of renewable
production is addressed in part 4, which
is focused on forecasting in the operational time frame. notably, one trend
that received extensive treatment is the
area of probabilistic forecasting, an important concept that developed through
an examination of probabilistic operational tools. The management of uncertainty is an area of growing interest
and will likely play a significant role
in future, but it is usually presented in
a manner that can be alienating to the
uninitiated; the authors do a good job of
explaining the concepts.
Moving through the book, the topics
change focus to planning for the flexibility that a system will need in the future.
The chapters focus on including flexibility concerns in long-term generation expansion planning, through to flexibility
assessment metrics and the technologies
that could enhance the flexibility of the
power system. The growing relevance
of demand response to the operation
is reflected in two chapters that show
the current value and potential significance of the resource as the transition

In an
environment
as fluid as we
find ourselves
in, good
information
is key.
