This book discusses dynamic modeling, simulation, and control
strategies for Photovoltaic (PV) stand-alone systems during
variation of environmental conditions. Moreover, the effectiveness
of the implemented Maximum Power Point Tracking (MPPT) techniques
and the employed control strategy are evaluated during variations
of solar irradiance and cell temperature. The simulation results
are based on the reliability of the MPPT techniques applied in
extracting the maximum power from the PV system during the rapid
variation of the environmental conditions. The authors review two
MPPT techniques implemented in PV systems, namely the perturb and
observe (P&O) MPPT Technique and the Incremental Conductance
(InCond) MPPT technique. These two MPPT techniques were simulated
by the MATLAB/Simulink and the results response of the PV array
from voltage, current, and power are compared to the effect of
solar irradiation and temperature change.

Energy has a wide range of uses within a country, includin socially
and economically. Providing everything from warmth and light to raw
materials for industrial production, energy is an essential need
for countries. Due to the importance of energy for countries,
energy policies are extremely vital, and energy needs to be
affordable, eco-friendly, and continuous so countries can provide
for their people and continue to develop industrially. Without the
availability of energy that is cheap and continuous, the
effectiveness in the energy supply process will be reduced, and
society will experience difficulties in having its daily energy
needs met. The Handbook of Research on Strategic Management for
Current Energy Investments analyzes current trends in energy
production and use and identifies energy investment strategies in
order to support affordable and available energy for all. Chapters
within the book cover technological developments that contribute to
the reduction of price in energy production as well as renewable
energy sources that provide continuity in energy production but do
not emit carbon into the atmosphere. This book highlights topics
that cover environmental pollution, energy pricing, economic
growth, carbon dioxide emission, and energy management. It is ideal
for engineers, technicians, managers, researchers, academicians,
policymakers, government officials, and students in related fields.
Placing emphasis on practical "how-to" guidance, this cutting-edge
resource provides a first-hand, insider's perspective on the advent
and evolution of smart grids in the 21st century. This book
presents engineers, researchers, and students with the building
blocks that comprise basic smart grids, including power plant,
transmission substation, distribution, and meter automation.
Moreover, this forward-looking volume explores the next step of
this technology's evolution. It provides a detailed explanation of
how an advanced smart grid incorporates demand response with smart
appliances and management mechanisms for distributed generation,
energy storage, and electric vehicles. This updated second edition
focuses on the disruptive impact of DER. This new edition also
includes a glossary with well over 100 acronyms and terms,
acknowledging the tremendous challenge for a student of smart
energy and smart grid to grasp this complex industry. Market
Practicing power engineers, academics, researchers, industry
analysts, and power regulators
Energy for today's complex electrical power systems is increasingly
being generated and distributed locally using small-scale,
renewable energy sources. The addition of renewables to the grid
requires new tools and operation methods, both for suppliers and
industrial consumers. This book describes the supporting
technologies that can turn conventional passive electricity
delivery networks into the active networks of the future, with a
focus on electricity utilization in the industrial environment. It
examines the integration of the new, dispersed sources with the
legacy systems of centralised generation, as well as how the new
technologies can operate effectively in isolated systems.
Industrial power distribution, lighting, motor control and
protection are discussed in detail. The presentation of the details
of the enabling technologies makes this book a valuable reference
for researchers, students and engineers involved in the planning,
design and installation of new systems or the upgrading of existing
ones.
This book presents advanced studies on the conversion efficiency,
mechanical reliability, and the quality of power related to wind
energy systems. The main concern regarding such systems is
reconciling the highly intermittent nature of the primary source
(wind speed) with the demand for high-quality electrical energy and
system stability. This means that wind energy conversion within the
standard parameters imposed by the energy market and power industry
is unachievable without optimization and control. The book
discusses the rapid growth of control and optimization paradigms
and applies them to wind energy systems: new controllers, new
computational approaches, new applications, new algorithms, and new
obstacles.
Conjugate methods, also sometimes referred to as coupled equations,
are used to analyze the inter-dependent relationship of two sets of
governing equations--for example in understanding the movement of
heat across the boundary from one object to another or the transfer
of energy from a moving fluid to a surrounding elastic medium. This
will be the first definitive text in years to offer a broad
overview of conjugate methods and their more typical applications,
with an emphasis on the advantages and benefits of this type of
engineering analysis. Students and professionals alike will gain a
better understanding of the practical uses for conjugate
mathematical methods in solving often intractable problems in heat
transfer and fluid mechanics. Ample end of chapter examples and
problem sets will help to reinforce the theory and knowledge
presented in the book. Some highlights are: Reviews basics of heat
conduction in solids and convective heat transfer Offers both
analytic and numerical methods for solving conjugate boundary
condition problems Numerous detailed examples of applications in
industrial problems, biomechanical systems, and other areas of heat
transfer and fluid mechanics End of chapter problems and Solutions

Transient events are short-lived bursts of energy in a system
resulting from a sudden change of the state. They can be caused by
faults, switching events or sudden changes in generation and load.
Given the need to expand HV cable grids and to interconnect
national grids to increase grid flexibility, the effects of such
transients need to be understood in order to maintain the security
of power supply and power quality. This book presents an overview
of formulas to model transients in cable systems based on complete
solutions of Maxwell's equations. It presents solutions to
particularly model important high frequency phenomena. The
impedance and admittance at a very low frequency for HVDC systems
are investigated. In addition, the modeling methods of underground
cables created in the Electromagnetic Transients Program (EMTP) are
described. Moreover, the wave propagation characteristics of
overhead lines and underground cables, and steady-state and
transient behaviour of three-phase cables are further investigated
in this book. Finally, transients in large interconnected HV cable
networks in Denmark and the Netherlands are presented as case
studies. Electromagnetic Transients in Large HV Cable Networks
enables researchers, HV system manufacturers and grid operators to
model, simulate and analyse transient phenomena in large HV cable
systems and to create solutions to counter and mitigate them.
Batteries are of vital importance for storing intermittent
renewable energy for stationary and mobile applications. In order
to charge the battery and maintain its capacity, the states of the
battery - such as the current charge, safety and health, but also
quantities that cannot be measured directly - need to be known to
the battery management system. State estimation estimates the
electrical state of a system by eliminating inaccuracies and errors
from measurement data. Numerous methods and techniques are used for
lithium-ion and other batteries. The various battery models seek to
simplify the circuitry used in the battery management system. This
concise work captures the methods and techniques for state
estimation needed to keep batteries reliable. The book focuses
particularly on mechanisms, parameters and influencing factors.
Chapters convey equivalent modelling and several Kalman filtering
techniques, including adaptive extended Kalman filtering for
multiple battery state estimation, dual extended Kalman filtering
prediction for complex working conditions, and particle filtering
of safety estimation considering the capacity fading effect. This
book is necessary reading for researchers in battery research and
development, including battery management systems and related power
electronics, for battery manufacturers, and for advanced students
in power electronics.
This is the first machine-generated scientific book in chemistry
published by Springer Nature. Serving as an innovative prototype
defining the current status of the technology, it also provides an
overview about the latest trends of lithium-ion batteries research.
This book explores future ways of informing researchers and
professionals. State-of-the-art computer algorithms were applied
to: select relevant sources from Springer Nature publications,
arrange these in a topical order, and provide succinct summaries of
these articles. The result is a cross-corpora auto-summarization of
current texts, organized by means of a similarity-based clustering
routine in coherent chapters and sections. This book summarizes
more than 150 research articles published from 2016 to 2018 and
provides an informative and concise overview of recent research
into anode and cathode materials as well as further aspects such as
separators, polymer electrolytes, thermal behavior and modelling.
With this prototype, Springer Nature has begun an innovative
journey to explore the field of machine-generated content and to
find answers to the manifold questions on this fascinating topic.
Therefore it was intentionally decided not to manually polish or
copy-edit any of the texts so as to highlight the current status
and remaining boundaries of machine-generated content. Our goal is
to initiate a broad discussion, together with the research
community and domain experts, about the future opportunities,
challenges and limitations of this technology.
Surface passivation of silicon solar cells describes a technology
for preventing electrons and holes to recombine prematurely with
one another on the wafer surface. It increases the cell's energy
conversion efficiencies and thus reduces the cost per kWh generated
by a PV system. In the past few years, new tools have been
developed to ensure low cost of ownership for high volume
production of passivated silicon solar cells. Different deposition
techniques (ALD, PECVD, APCVD) and different materials (SiO2,
Al2O3, Si3N4) have been tested during the development process of
more than 10 years. Now, the silicon solar cell manufacturing
industry is picking up the concept of rear side passivation. The
next generation silicon solar cells in production will be the PERC
(Passivated Emitter and Rear Cell) type using all the reported
achievements including novel tool concepts and process
technologies. This timely overview of silicon solar cell surface
passivation, written by the leading experts in the field, is a key
read for students and researchers working with silicon solar cells,
as well as solar cell manufacturers.
Waste to Energy deals with the very topical subject of converting
the calorific content of waste material into useful forms of
energy. It complements and, to a certain degree, overlaps with its
companion volume, "Biomass to Biofuels", since a significant
proportion of biomass converted to energy nowadays originates from
various types of waste. The material in the first, more substantial
part of the volume has been arranged according to the type of
process for energy conversion. Biochemical processes are described
in six articles. These relate to the production of methane by
anaerobic digestion; reactor conversion efficiencies;
investigations on ethanol production from biodegradable municipal
solid waste through hydrolysis and fermentation; hydrogen
production from glucose through a hybrid anaerobic and
photosynthetic process; biodiesel production from used cooking oil
through base-catalyzed transesterification. Conversions by
thermochemical processes are discussed in the subsequent eleven
articles of the volume.These cover combustion, the direct use of
heat energy; using the heat produced in thermal power stations for
steam and, ultimately, electricity generation; municipal solid
waste and refuse-derived fuel. In another article, computational
fluid dynamics modelling is applied to assess the influence of
process parameters and to perform optimization studies. A group of
articles deal with more complex thermochemical processes involving
combustion combined with pyrolysis and gasification. Two articles
focus on biofuels as feed for fuel cells. In the last six articles,
the emphasis is on management and policy rather than technical
issues.
