Power Transmission System Analysis Against Faults and Attacks
by Abhijit Chakrabarti Chandan Kumar Chanda Tamalika ChowdhuryThe present-day power grid is basically a complex power transmission network with risks of failure due to unplanned attacks and contingencies, and therefore, assessment of vulnerability of transmission network is important and the process is based on contingency approach. This book deals with the methods of assessment of the grid network vulnerability and addresses the grid collapse problem due to cascaded failures of the transmission network following an attack or an unplanned contingency. Basic mitigation aspects for the network has been explored and the immunity of such a power transmission network against vulnerable collapse has been described using mathematical models.
Power Transmissions: Proceedings of the 4th International Conference, held at Sinaia, Romania, June 20 -23, 2012
by George Dobre Mihai Robert VladuThis books contains the Proceedings of the 4th International Conference on Power Transmissions, that was held in Sinaia, Romania from June 20 -23, 2012. Power Transmissions is a very complex and multi-disciplinary scientific field of Mechanical Engineering that covers the different types of transmissions (mechanical, hydraulic, pneumatic) as well as all the machine elements involved, such as gears, bearings, shafts, couplings and a lot more. It concerns not only their basic theory but also their design, analysis, testing, application and maintenance. The requirements set to modern power transmissions are really tough to meet: They need to be more efficient, stronger, smaller, noiseless, easier to produce and to cost less. There is a strong demand to become easier in operation and maintenance, or even automatic and in maintenance-free. Last but not least, they should be easily recycled and respect the environment. Joint efforts of specialists from both academia and industry can significantly contribute to fulfill these needs. The main goal of this conference was to bring together experts from all over the world and present the latest developments in the field of Power Transmissions.

Power Trip: The Story of Energy
by Michael E. WebberA global tour of energy--the builder of human civilization and also its greatest threat.Energy is humanity's single most important resource. In fact, as energy expert Michael E. Webber argues in Power Trip, the story of how societies rise can be told largely as the story of how they manage energy sources through time. In 2019, as we face down growing demand for and accumulating environmental impacts from energy, we are at a crossroads and the stakes are high. But history shows us that energy's great value is that it allows societies to reinvent themselves. Power Trip explores how energy has transformed societies of the past and offers wisdom for today's looming energy crisis. There is no magic bullet; energy advances always come with costs. Scientific innovation needs public support. Energy initiatives need to be tailored to individual societies. We must look for long-term solutions. Our current energy crisis is real, but it is solvable. We have the power.

Power after Carbon: Building a Clean, Resilient Grid
by Peter Fox-PennerAs the electric power industry faces the challenges of climate change, technological disruption, new market imperatives, and changing policies, a renowned energy expert offers a roadmap to the future of this essential sector. As the damaging and costly impacts of climate change increase, the rapid development of sustainable energy has taken on great urgency. The electricity industry has responded with necessary but wrenching shifts toward renewables, even as it faces unprecedented challenges and disruption brought on by new technologies, new competitors, and policy changes. The result is a collision course between a grid that must provide abundant, secure, flexible, and affordable power, and an industry facing enormous demands for power and rapid, systemic change. The fashionable solution is to think small: smart buildings, small-scale renewables, and locally distributed green energy. But Peter Fox-Penner makes clear that these will not be enough to meet our increasing needs for electricity. He points instead to the indispensability of large power systems, battery storage, and scalable carbon-free power technologies, along with the grids and markets that will integrate them. The electric power industry and its regulators will have to provide all of these, even as they grapple with changing business models for local electric utilities, political instability, and technological change. Power after Carbon makes sense of all the moving parts, providing actionable recommendations for anyone involved with or relying on the electric power system.

Power and Gas Asset Management: Regulation, Planning and Operation of Digital Energy Systems (Lecture Notes in Energy #72)
by Miguel Moreira da SilvaThis book offers meaningful insights into an impending challenge for the energy industry, namely the increasing role of asset management amongst the utilities’ core operations. In the aftermath of energy digitalization, power and gas companies will be able to seize asset productivity—through risk-based operation and maintenance—and better balance capital and operational expenditures. By addressing the asset management of both power and gas infrastructures, and by adopting a comprehensive approach—including regulation and business models, as well as a solid technology background—this book offers a unique perspective on the energy utilities’ transformation journey and the road to optimal decision-making for both asset portfolio expansion and replacement. The asset management end-to-end mission requires appropriate internal governance—depending on the business framework—and the development of decision aid models (for asset replacement and maintenance), supported on probabilistic risk and reliability indexes. This book advocates systematically digitalizing the power and gas assets, addressing both data governance and infrastructure, alongside real-time equipment condition monitoring. It also provides a meaningful methodology for designing data-centric asset management and predictive operation and maintenance, using artificial intelligence and engineering-based approaches. As such, it provides valuable strategy, methods and models—illustrated by case studies and proofs of concept—for a wide range of stakeholders, including utilities and industry professionals, regulators, policy-makers, researchers and students.
Power and Powerlessness: Quiescence and Rebellion in an Appalachian Valley

Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity
by Simon Johnson Daron AcemogluThe bestselling co-author of Why Nations Fail and the bestselling co-author of 13 Bankers deliver a bold reinterpretation of economics and history that will fundamentally change how you see the world A thousand years of history and contemporary evidence make one thing clear: progress depends on the choices we make about technology. New ways of organizing production and communication can either serve the narrow interests of an elite or become the foundation for widespread prosperity. The wealth generated by technological improvements in agriculture during the European Middle Ages was captured by the nobility and used to build grand cathedrals, while peasants remained on the edge of starvation. The first hundred years of industrialization in England delivered stagnant incomes for working people. And throughout the world today, digital technologies and artificial intelligence undermine jobs and democracy through excessive automation, massive data collection, and intrusive surveillance. It doesn&’t have to be this way. Power and Progress demonstrates the path of technology was once—and may again—be brought under control. Cutting-edge technological advances can become empowering and democratizing tools, but not if all major decisions remain in the hands of a few hubristic tech leaders. With their bold reinterpretation of economics and history, Daron Acemoglu and Simon Johnson fundamentally change how we see the world, providing the vision needed to redirect innovation so it again benefits most people.
Power and the Vote
by Brian MinHow do developing states decide who gets access to public goods like electricity, water, and education? Power and the Vote breaks new ground by showing that the provision of seemingly universal public goods is intricately shaped by electoral priorities. In doing so, this book introduces new methods using high-resolution satellite imagery to study the distribution of electricity across and within the developing world. Combining cross-national evidence with detailed sub-national analysis and village-level data from India, Power and the Vote affirms the power of electoral incentives in shaping the distribution of public goods and challenges the view that democracy is a luxury of the rich with little relevance to the world's poor.

Power from the People: How to Organize, Finance, and Launch Local Energy Projects
by Greg Pahl"Over 90 percent of US power generation comes from large, centralized, highly polluting, nonrenewable sources of energy. It is delivered through long, brittle transmission lines, and then is squandered through inefficiency and waste. But it doesn't have to be that way. Communities can indeed produce their own local, renewable energy. Power from the People explores how homeowners, co-ops, nonprofit institutions, governments, and businesses are putting power in the hands of local communities through distributed energy programs and energy-efficiency measures. Using examples from around the nation - and occasionally from around the world - Greg Pahl explains how to plan, organize, finance, and launch community-scale energy projects that harvest energy from sun, wind, water, and earth. He also explains why community power is a necessary step on the path to energy security and community resilience - particularly as we face peak oil, cope with climate change, and address the need to transition to a more sustainable future. This book - the second in the Chelsea Green Publishing Company and Post Carbon Institute's Community Resilience Series - also profiles numerous communitywide initiatives that can be replicated elsewhere.

Power over Peoples
by Daniel R. HeadrickFor six hundred years, the nations of Europe and North America have periodically attempted to coerce, invade, or conquer other societies. They have relied on their superior technology to do so, yet these technologies have not always guaranteed success. Power over Peoples examines Western imperialism's complex relationship with technology, from the first Portuguese ships that ventured down the coast of Africa in the 1430s to America's conflicts in the Middle East today. Why did the sailing vessels that gave the Portuguese a century-long advantage in the Indian Ocean fail to overcome Muslim galleys in the Red Sea? Why were the same weapons and methods that the Spanish used to conquer Mexico and Peru ineffective in Chile and Africa? Why didn't America's overwhelming air power assure success in Iraq and Afghanistan? In Power over Peoples, Daniel Headrick traces the evolution of Western technologies--from muskets and galleons to jet planes and smart bombs--and sheds light on the environmental and social factors that have brought victory in some cases and unforeseen defeat in others. He shows how superior technology translates into greater power over nature and sometimes even other peoples, yet how technological superiority is no guarantee of success in imperialist ventures--because the technology only delivers results in a specific environment, or because the society being attacked responds in unexpected ways. Breathtaking in scope, Power over Peoples is a revealing history of technological innovation, its promise and limitations, and its central role in the rise and fall of empire.
Power to the Public: The Promise of Public Interest Technology
by Hana Schank Tara Dawson McGuinnessA powerful new blueprint for how governments and nonprofits can harness the power of digital technology to help solve the most serious problems of the twenty-first centuryAs the speed and complexity of the world increases, governments and nonprofit organizations need new ways to effectively tackle the critical challenges of our time—from pandemics and global warming to social media warfare. In Power to the Public, Tara Dawson McGuinness and Hana Schank describe a revolutionary new approach—public interest technology—that has the potential to transform the way governments and nonprofits around the world solve problems. Through inspiring stories about successful projects ranging from a texting service for teenagers in crisis to a streamlined foster care system, the authors show how public interest technology can make the delivery of services to the public more effective and efficient.At its heart, public interest technology means putting users at the center of the policymaking process, using data and metrics in a smart way, and running small experiments and pilot programs before scaling up. And while this approach may well involve the innovative use of digital technology, technology alone is no panacea—and some of the best solutions may even be decidedly low-tech.Clear-eyed yet profoundly optimistic, Power to the Public presents a powerful blueprint for how government and nonprofits can help solve society’s most serious problems.
