The energy transition initiated in recent years has enabled the
growing integration of renewable production into the energy mix.
Microgrids make it possible to maximize the efficiency of energy
transmission from source to consumer by bringing the latter
together geographically and by reducing losses linked to transport.
However, the lack of inertia and the micro-grid support system
makes it weak, and energy storage is necessary to ensure its proper
functioning. Current storage technologies do not make it possible
to provide both a large capacity of energy and power at the same
time. Hybrid storage is a solution that combines the advantages of
several technologies and reduces their disadvantages. Modeling and
Control of Static Converters for Hybrid Storage Systems covers the
modeling, control theorems, and optimization techniques that solve
many scientific problems for researchers in the field of power
converter control for renewable energy hybrid storage and places
particular emphasis on the modeling and control of static
converters for hybrid storage systems. Covering topics ranging from
energy storage to power generation, this book is ideal for
automation engineers, electrical engineers, mechanical engineers,
professionals, scientists, academicians, master's and doctoral
students, and researchers in the disciplines of electrical and
mechanical engineering.
The book systematically introduces smart power system design and
its infrastructure, platform and operating standards. It focuses on
multi-objective optimization and illustrates where the intelligence
of the system lies. With abundant project data, this book is a
practical guideline for engineers and researchers in electrical
engineering, as well as power network designers and managers in
administration.
COMSOL 5 and MATLAB are valuable software modeling tools for
engineers and scientists. This updated edition includes five new
models and explores a wide range of models in coordinate systems
from 0D to 3D, introducing the numerical analysis techniques
employed in COMSOL 5.6 and MATLAB software. The text presents

This book outlines the principles of thermoelectric generation and
refrigeration from the discovery of the Seebeck and Peltier effects
in the nineteenth century through the introduction of semiconductor
thermoelements in the mid-twentieth century to the more recent
development of nanostructured materials. It is shown that the
efficiency of a thermoelectric generator and the coefficient of
performance of a thermoelectric refrigerator can be related to a
quantity known as the figure of merit. The figure of merit depends
on the Seebeck coefficient and the ratio of the electrical to
thermal conductivity. It is shown that expressions for these
parameters can be derived from the band theory of solids. The
conditions for favourable electronic properties are discussed. The
methods for selecting materials with a low lattice thermal
conductivity are outlined and the ways in which the scattering of
phonons can be enhanced are described. The application of these
principles is demonstrated for specific materials including the
bismuth telluride alloys, bismuth antimony, alloys based on lead
telluride, silicon-germanium and materials described as
phonon-glass electron-crystals. It is shown that there can be
advantages in using the less familiar transverse thermoelectric
effects and the transverse thermomagnetic effects. Finally,
practical aspects of thermoelectric generation and refrigeration
are discussed. The book is aimed at readers who do not have a
specialised knowledge of solid state physics.
Smart technology has significantly enhanced the efficient
management of electric power supply systems. Despite the benefits
