Book Description
This book describes an original improvement in power quality of photovoltaic generation systems obtained by the use of a multilevel inverter implemented with level doubling network (LDN). Modulation principles and harmonic analysis of output voltages are proposed and introduced in detail for both single and three-phase LDN configurations. The analysis is then extended to dc-link current and voltage, with emphasis to low-frequency harmonics and switching frequency ripple. This work represents the first comprehensive implementation of maximum power point tracking (MPPT) schemes using the ripple correlation control (RCC) algorithm in the presence of multiple ripple harmonics, such as in the case of multilevel inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors.

Book Description
This book outlines issues related to massive integration of electric and plug-in hybrid electric vehicles into power grids. Electricity is becoming the preferred energy vector for the next new generation of road vehicles. It is widely acknowledged that road vehicles based on full electric or hybrid drives can mitigate problems related to fossil fuel dependence. This book explains the emerging and understanding of storage systems for electric and plug-in hybrid vehicles. The recharging stations for these types of vehicles might represent a great advantage for the electric grid by facilitating integration of renewable and distributed energy production. This book presents a broad review from analyzing current literature to on-going research projects about the new power technologies related to the various charging architectures for electric and plug-in hybrid vehicles. Specifically focusing on DC fast charging operations, as well as, grid-connected power converters and the full range of energy storage systems. These key components are analyzed for distributed generation and charging system integration into micro-grids. The authors demonstrate that these storage systems represent effective interfaces for the control and management of renewable and sustainable distributed energy resources. New standards and applications are emerging from micro-grid pilot projects around the world and case studies demonstrate the convenience and feasibility of distributed energy management. The material in this unique volume discusses potential avenues for further research toward achieving more reliable, more secure and cleaner energy.

Book Description
Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support. This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor. With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues: modern grid inverter topologies for photovoltaic and wind turbines islanding detection methods for photovoltaic systems synchronization techniques based on second order generalized integrators (SOGI) advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques power control under grid fault conditions, considering both positive and negative sequences Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry.

Book Description
"The story of the Jews in twentieth-century Russia as told through the strange history of the Soviet solution to the Jewish question. In 1929, the Soviet Union declared the area of Birobidzhan a homeland for Jews. In the late 1920s and early 1932, tens of thousands of Jews moved to Birobidzhan, chased from the shtetl by poverty, hunger, and fear. Birobidzhan was written about breathlessly by a small group of intellectuals who envisioned a home built by Jews for Jews--a place where Jews worked the land and where Yiddish would become the common language of a post-oppression Jewish culture. The short period of state-building ended in the late 1930s with arrests and purges of the Communist Party and cultural elite. After the Second World War, Birobidzhan, now called the "Jewish Autonomous Region," received a new influx of Jews. These were the dispossessed from what had once been the Pale, and most of them had lost families in the Holocaust. They had no one and no place to return to. Once again, in the late 1940s, a wave of arrests swept through Birobidzhan, frightening the Jews into silence and making them invisible. WHERE THE JEWS AREN'T is the story of the dream of Birobidzhan--and how it became a nightmare. In Masha Gessen's haunting and haunted account, Birobidzhan becomes the cracked and crooked mirror that allows us to see the story of the history of absence and silence that is the story of Jews in twentieth-century Russia"--
