Unlike conventional power plants, wind plants emit no air
pollutants or greenhouse gases-and wind energy is a free, renewable
resource. However, the induction machines commonly used as wind
generators have stability problems similar to the transient
stability of synchronous machines. To minimize power, frequency,
and voltage fluctuations caused by network faults or random wind
speed variations, control mechanisms are necessary. Wind Energy
Systems: Solutions for Power Quality and Stabilization clearly
explains how to solve stability and power quality issues of wind
generator systems. Covering fundamental concepts of wind energy
conversion systems, the book discusses several means to enhance the
transient stability of wind generator systems. It also explains the
methodologies for minimizing fluctuations of power, frequency, and
voltage. Topics covered include: An overview of wind energy and
wind energy conversion systems Fundamentals of electric machines
and power electronics Types of wind generator systems Challenges in
integrating wind power into electricity grids Solutions for power
quality problems Methods for improving transient stability during
network faults Methods for minimizing power fluctuations of
variable-speed wind generator systems This accessible book helps
researchers and engineers understand the relative effectiveness of
each method and select a suitable tool for wind generator
stabilization. It also offers students an introduction to wind
energy conversion systems, providing insights into important grid
integration and stability issues.

Against the background of long-standing narratives in which Twelver
Shiâism is viewed as fundamentally authoritarian, The School of
Hillah and the Formation of Twelver Shiâi Islamic Tradition
builds upon recent scholarship in the fields of Religious Studies,
Anthropology, and History to argue that Twelver Shiâism is better
understood as a discursive tradition. At a conceptual level, this
solves the basic problem of how to integrate the extraordinary
diversity of Twelver Shiâism across time and space into a single
historical category without engaging in a normative assessment of
its underlying essence. Furthermore, in light of this conception of
tradition, the School of Hillah stands out as a seminal period in
the archive of Twelver Shiâism, though it has seldom been
recognized as such in European-language scholarship. Insofar as it
gave birth to a conversation that would prove capable of
encompassing the dynamism of Twelver Shiâism, the School of
Hillah should be considered the formative period of Twelver Shiâi
tradition. Moreover, when the tradition is conceptualized in this
manner, it is a bulwark against the very authoritarianism by which
Twelver Shiâism has been characterized for so long.
Energy storage is key to integrating renewable power.
Superconducting magnetic energy storage (SMES) systems store power
in the magnetic field in a superconducting coil. Once the coil is
charged, the current will not stop and the energy can in theory be
stored indefinitely. This technology avoids the need for lithium
for batteries. The round-trip efficiency can be greater than 95%,
but energy is needed for the cooling of the superconducting coil,
and the material is expensive. So far, SMES systems are primarily
used for improving power quality through short time storage, but
further applications are being researched. This concise treatise
for researchers, including PhD students, involved with energy
storage research at universities and in industry, experts at
utilities and grid operators, as well as advanced students provides
a hands-on overview of SMES technology. Chapters cover principles,
control, power quality and transient stability enhancement, load
frequency control, dynamic performance, use of AI with SMES, and
cybersecurity case studies underpin the coverage.

'A knotty, postmodern tale. The quicksilver narrative slips between dream, memory and reality ... A beguiling enigma' Financial Times
In an Anatolian village forgotten both by God and the government, the muhtar has been elected leader for the sixteenth successive year. When he staggers to bed that night, drunk on raki and his own well-deserved success, the village is prosperous. But when he is woken by his wife the next evening he discovers that Nuri, the barber, has disappeared without a trace in the dead of night, and the community begins to fracture.
In a nameless town far, far away, Nuri walks into a barbershop as if from a dream, not knowing how he has arrived. Try as he might, he cannot grasp the strands of his memory. The facts of his past life shift and evade him, and as other customers come and go, they too struggle to recall how they got there.
Blurring the lines of reality to terrific effect, Shadowless is both a compelling mystery and an enduring evocation of displacement from one of the finest, most exciting voices in Turkish literature today.
