Battery Management System for Microgrids
System has two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, applied to hybrid system. When load is light, the UPC mode is selected. In UPC mode variation in load demands are compensated by the main grid because the hybrid source output is regulated to reference power. In FFC mode feeder flow is regulated to a constant power, the extra load demand is picked up by hybrid sources and hence feeder reference power must be known. The system can maximize the generated power when load is heavy and minimizes the load shedding area.The proposed operating strategies with flexible operation mode change always operates the photovoltaic array at maximum output power and battery in its high efficiency performance band, thus improving the performance of system operation, enhance system stability, decreasing the number of operating mode changes in the MATLAB Simulink environmen

Analysis And Suppression Of Transient Over-Voltages In GIS
In our country a few Gas Insulated Substations (GIS) units have been in operation and large number of units are under various stages of installation. Although GIS have been in operation for several years, some of the problems need attention. These problems include, generation of over voltage during dis-connector operations, line to enclosure faults etc. These over voltages are caused in two ways, viz., due to switching operations of circuit breaker and line to enclosure faults. In the project work, very fast transient over voltages are generated due to switching operations have been analyzed and presented. Since the contact speed of dis-connector switches is low, re-striking occurs many times before the current interruption is completed. Each re-striking generates transient over voltage with different levels of magnitude. Since these transients have traveling wave behavior, they travel to the external systems through enclosures, bushings, cable joints etc., and cause damage to the outside equipment. They can lead to secondary break downs in GIS and may give rise to electromagnetic interference.It is important to develop a suitable simulation models for estimation of these voltages.

The Invisible Rainbow
5g is being rolled out across the country, despite growing evidence that it is disruptive to our health, our safety, and the environment. The Invisible Rainbow is the groundbreaking story of electricity as it's never been told before--exposing its very real impact on the biosphere and human health. 100,000 copies sold! Over the last 220 years, society has evolved a universal belief that electricity is 'safe' for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before--from an environmental point of view--by detailing the effects that this fundamental societal building block has had on our health and our planet. In The Invisible Rainbow, Firstenberg traces the history of electricity from the early eighteenth century to the present, making a compelling case that many environmental problems, as well as the major diseases of industrialized civilization--heart disease, diabetes, and cancer--are related to electrical pollution. "Few individuals today are able to grasp the entirety of a scientific subject and present it in a highly engaging manner . . . Firstenberg has done just that with one of the most pressing but neglected problems of our technological age."--BRADLEY JOHNSON, MD, Amen Clinic, San Francisco "[A] masterpiece."--Celia Farber, investigative journalist "This seminal book...will transform your understanding ...of the environmental and health effects of electricity and radio frequencies"--Paradigm Explorer
The Inventions- Researches- and Writings of Nikola Tesla
The early works of famed inventor Nikola Tesla, and a source of inspiration for generations of innovators. At the time it was first published in 1893, The Inventions, Researches, and Writings of Nikola Tesla was considered the bible of electrical engineering and inspired generations of inventors. This volume, edited by Tesla's contemporary, Thomas Commerford Martin, includes extensive discussion of Tesla's early work and inventions and contains more than 300 illustrations that demonstrate the practical application of his ideas. Tesla, who was born in what is now Croatia, is best known for his research into the use of high-frequency alternating currents and wireless transmission. Many of his ideas have found practical application in the modern world, and he continues to be a source of inspiration and fascination to this day.
The Grid
One of Bill Gates's Favorite Books of 2016 A revelatory look at our national power grid--how it developed, its current flaws, and how it must be completely reimagined for our fast-approaching energy future. America's electrical grid, an engineering triumph of the twentieth century, is turning out to be a poor fit for the present. It's not just that the grid has grown old and is now in dire need of basic repair. Today, as we invest great hope in new energy sources--solar, wind, and other alternatives--the grid is what stands most firmly in the way of a brighter energy future. If we hope to realize this future, we need to reimagine the grid according to twenty-first-century values. It's a project which forces visionaries to work with bureaucrats, legislators with storm-flattened communities, moneymen with hippies, and the left with the right. And though it might not yet be obvious, this revolution is already well under way. Cultural anthropologist Gretchen Bakke unveils the many facets of America's energy infrastructure, its most dynamic moments and its most stable ones, and its essential role in personal and national life. The grid, she argues, is an essentially American artifact, one which developed with us: a product of bold expansion, the occasional foolhardy vision, some genius technologies, and constant improvisation. Most of all, her focus is on how Americans are changing the grid right now, sometimes with gumption and big dreams and sometimes with legislation or the brandishing of guns. The Grid tells--entertainingly, perceptively--the story of what has been called "the largest machine in the world" its fascinating history, its problematic present, and its potential role in a brighter, cleaner future.
It Is Quite Another Electricity
This book is a description by the author of the proposed single-wire transmission system. The system can operate at any frequency, including DC. It can be applied to a three-phase transmission signal and to collect energy from the "green" sources. It describes in detail the problems associated with zeroing (grounding) signal and energy transfer on the underground and underwater lines. There is data on two experimental systems.

Shocking Bodies
From electric corsets to questioning the existence of God, the story of the profound effects electricity had upon the lives and the worldview of the Victorians Although electricity was known about by the ancient Egyptians, it was not until the Victorian era that its potential really began to be realized. Luigi Galvani's discovery of bioelectricity opened up a whole new world of possibilities, in which it could cure sickness, restore sexual potency, and even raise the dead. This book explores how the Victorians thought about electricity, and how they tried to use it to answer the fundamental questions about life and death. It discusses the beliefs they came into being about electricity--some believed that it was life, which brought into question the existence of the soul, and of God, and provided arguments in favor of political Radicalism. Doctors prescribed electrical therapy and the masses were offered electric belts or corsets, at a price, that were claimed to have amazing restorative properties. This is the story of how electricity emerged during the 19th century as a powerful new tool for making sense of the world.
Findings on Elasticity
The second issue in the exciting and experimental cross-disciplinary series Findings on... by Astrid van Baalen and Hester Aardse from the Pars Foundation is centred on ELASTICITY in the broadest sense of the word.What happens when one gives a simple rubber band to an architect, historian, choreographer, chemist, artist, mathematician, physicist, economist, anthropologist, and geologist and asks each of them for a statement on elasticity? The economist studies the elasticity of supply and demand of market forces. The architect calculates the elasticity of the steel structure of a building during an earthquake. The anthropologist studies the flow of people returning to their homes in the wake of a natural disaster. The choreographer pushes the elasticity of his dancers' movements as they rehearse a new dance. The Pars Foundation draws researchers out of their specialized niches in order to publish their brilliant, crazy, important, or bewildering results and assembles them in this interdisciplinary volume. Findings on Elasticity is the second part of a publication series that together will constitute an atlas of creative thinking. There are no guidelines for the form their contributions must take. It may be images, poems, essays, sketches on coasters, formulas, a piece of sculpture or a piece of string; the editors only ask that a contribution reflect the respondent's own field as well as his or her passion for the topic.
Explorative Experimente
Vor dem Hintergrund der neueren Experimentforschungen der Wissenschaftsgeschichte wird die Selbstdarstellung der Naturwissenschaft im 19. Jahrhundert hinterfragt und dazu die Arbeits- und Aufzeichnungspraxis von Physikern in Labornotizen und Briefen, Zeichnungen und Rechnungen rekonstruiert. In der Fruhphase der Elektrodynamik (1820-1822) wurden die begrifflichen Grundlagen fur die Fernwirkungstheorie und die Feldtheorie geschaffen, deren Dichotomie eines der zentralen Themen der Physik des 19. Jahrhunderts darstellte. Im Zentrum stehen die Protagonisten Ampere und Faraday, die in unterschiedlichen Arbeitskontexten, aber mit Blick auf dasselbe Forschungsgebiet, verschiedene Wege experimenteller Forschung einschlugen und dabei divergierende Ordnungssysteme entwickelten. Bei beiden findet sich eine explorative, der historischen und philosophischen Analyse bislang entgangene experimentelle Arbeitsweise. Die Arbeit gibt erstmals ein Gesamtbild einer zentralen Phase der Physikgeschichte und schlagt ein neues Verstandnis des Experiments als Mittel empirischer Forschung vor.
Empires Of Light
The gripping history of electricity and how the fateful collision of Thomas Edison, Nikola Tesla, and George Westinghouse left the world utterly transformed. In the final decades of the nineteenth century, three brilliant and visionary titans of America's Gilded Age--Thomas Edison, Nikola Tesla, and George Westinghouse--battled bitterly as each vied to create a vast and powerful electrical empire. In Empires of Light, historian Jill Jonnes portrays this extraordinary trio and their riveting and ruthless world of cutting-edge science, invention, intrigue, money, death, and hard-eyed Wall Street millionaires. At the heart of the story are Thomas Alva Edison, the nation's most famous and folksy inventor, creator of the incandescent light bulb and mastermind of the world's first direct current electrical light networks; the Serbian wizard of invention Nikola Tesla, elegant, highly eccentric, a dreamer who revolutionized the generation and delivery of electricity; and the charismatic George Westinghouse, Pittsburgh inventor and tough corporate entrepreneur, an industrial idealist who in the era of gaslight imagined a world powered by cheap and plentiful electricity and worked heart and soul to create it. Edison struggled to introduce his radical new direct current (DC) technology into the hurly-burly of New York City as Tesla and Westinghouse challenged his dominance with their alternating current (AC), thus setting the stage for one of the eeriest feuds in American corporate history, the War of the Electric Currents. The battlegrounds: Wall Street, the 1893 Chicago World's Fair, Niagara Falls, and, finally, the death chamber--Jonnes takes us on the tense walk down a prison hallway and into the sunlit room where William Kemmler, convicted ax murderer, became the first man to die in the electric chair.
