Electricity Network Regulation in the EU - The Challenges Ahead  for Transmission and Distribution (Hardcover): Leonardo Meeus,... Electricity Network Regulation in the EU - The Challenges Ahead for Transmission and Distribution (Hardcover)
Leonardo Meeus, Jean-Michel Glachant
R2,201 Discovery Miles 22 010 Ships in 10 - 15 working days

The UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong regulatory authority, and limited coordination between foreign grid operators. This enlightening book demonstrates how the landscape has changed markedly since 2010 and that regulation has had to work hard to catch up and evolve. As the EU enters a wave of investment and an era of new services and innovation, this has created growing tensions between national regulatory authorities in terms of coordinating technical standards and distribution systems. This is being played out against an increasingly disruptive backdrop of digitization, new market platforms and novel business models. Electricity Network Regulation in the EU adopts a truly European approach to the complex issues surrounding the topic, focusing on the grey areas and critical questions that have traditionally been difficult to answer. Incentive regulation and grids are addressed simultaneously at the theoretical and practical level, providing the reader with fundamental concepts and concrete examples. This timely book is an invaluable read for energy practitioners working in utility companies, regulators and other public bodies. It will also appeal to academics involved in the world of electricity regulation. The book utilizes language that would make it suitable for interdisciplinary students, including engineering and law scholars.

R745 R595 Discovery Miles 5 950 Save R150 (20%) Ships in 7 - 11 working days

The former Purdue Power Plant (HPN) with its iconic smoke stack and the attached Engineering Administration Building (ENAD) at the very heart of campus played important roles for most of the twentieth century. To many Purdue students and alumni, the smoke stack not only symbolized the emphasis at Purdue on technology but also provided a visible marker for the Purdue campus. The smoke stack was lovingly referred to by many as "Purdue's finger to the world." Amid controversy, the smoke stack was demolished in the early 1990s when the Purdue Clock Tower was constructed to locate the campus on the landscape. A Purdue Icon: Creation, Life, and Legacy is an edited volume that speaks to the history of the Power Plant, from the initial need for increased power and heat to meet a growing campus demand and its Romanesque architecture that allowed it to fit contextually on the campus, to the people who worked to bring heat and power to the campus by keeping the boilers up and the students who experienced the principles and applications of mechanical engineering through active learning. This book tells the story of the transition to alternative power and heat sources at the University, the decommissioning of the Power Plant, the controversy about what was to be done with this important site at the heart of the campus, and the challenges associated with the Power Plant's potential reuse or demolition. The unique problems faced with demolishing a contaminated building in the middle of a major research university campus are insightfully explored before introducing the Thomas S. and Harvey D. Wilmeth Active Learning Center-a potential new Purdue icon.

In recognition of the fact that billions of people in the developing world do not have access to clean energies, the United Nations launched the Sustainable Energy for All Initiative to achieve universal energy access by 2030. Although electricity grid extension remains the most prevalent way of providing access, it is now recognized that the central grid is unlikely to reach many remote areas in the near future. At the same time, individual solutions like solar home systems tend to provide very limited services to consumers. Mini-grids offer an alternative by combining the benefits of a grid-based solution with the potential for harnessing renewable energies at the local level. The purpose of this book is to provide in-depth coverage of the use of mini-grids for rural electrification in developing countries, taking into account the technical, economic, environmental and governance dimensions and presenting case studies from South Asia.

This book reports on research carried out by a consortium of British and Indian researchers on off-grid electrification in South Asia. It provides state-of-the art technical knowledge on mini-grids and micro-grids including renewable energy integration (or green mini-grids), smart systems for integration with the central grid, and standardization of systems. It also presents essential analytical frameworks and approaches that can be used to analyze the mini-grids comprehensively including their techno-economic aspects, financial viability and regulatory issues. The case studies drawn from South Asia demonstrate the application of the framework and showcase various successful efforts to promote mini-grids in the region. It also reports on the design and implementation of a demonstration project carried out by the team in a cluster of villages in Odisha (India).

The book's multi-disciplinary approach facilitates understanding of the relevant practical dimensions of mini-grid systems, such as demand creation (through interventions in livelihood generation and value chain development), financing, regulation, and smart system design. Its state-of-the art knowledge, integrated methodological framework, simulation exercises and real-life case analysis will allow the reader to analyze and appreciate the mini-grid-related activities in their entirety. The book will be of interest to researchers, graduate students, practitioners and policy makers working in the area of rural electrification in developing countries.

This book addresses the design challenges in near-field wireless power transfer (WPT) systems, such as high efficiency, compact size, and long transmission range. It presents new low-profile designs for the TX/RX structures using different shapes of defected ground structures (DGS) like (H, semi-H, and spiral-strips DGS). Most near-field WPT systems depend on magnetic resonant coupling (MRC) using 3-D wire loops or helical antennas, which are often bulky. This, in turn, poses technical difficulties in their application in small electronic devices and biomedical implants. To obtain compact structures, printed spiral coils (PSCs) have recently emerged as a candidate for low-profile WPT systems. However, most of the MRC WPT systems that use PSCs have limitations in the maximum achievable efficiency due to the feeding method. Inductive feeding constrains the geometric dimensions of the main transmitting (TX)/receiving (RX) resonators, which do not achieve the maximum achievable unloaded quality factor. This book will be of interest to researchers and professionals working on WPT-related problems.

This book presents a general framework for modelling power system devices to develop complete electromechanical models for synchronous machines, induction machines, and power electronic devices. It also presents linear system analysis tools that are specific to power systems and which are not generally taught in undergraduate linear system courses. Lastly, the book covers the application of the models, analysis and tools to the design of automatic voltage controllers and power system stabilisers, both for single-machine-infinite-bus systems and multi-machine interconnected systems. In most textbooks modelling, dynamic analysis, and control are closely linked to the computation methods used for analysis and design. In contrast, this book separates the essential principles and the computational methods used for power system dynamics and control. The clear distinction between principles and methods makes the potentially daunting task of designing controllers for power systems much easier to approach. A rich set of exercises is also included, and represents an integral part of the book. Students can immediately apply-using any computational tool or software-the essential principles discussed here to practical problems, helping them master the essentials.

This brief examines issues of spectrum allocation for the limited resources of radio spectrum. It uses a game-theoretic perspective, in which the nodes in the wireless network are rational and always pursue their own objectives. It provides a systematic study of the approaches that can guarantee the system's convergence at an equilibrium state, in which the system performance is optimal or sub-optimal. The author provides a short tutorial on game theory, explains game-theoretic channel allocation in clique and in multi-hop wireless networks and explores challenges in designing game-theoretic mechanisms for dynamic channel redistribution. Since designing a completely secure mechanism is extremely expensive or impossible in most of distributed autonomous systems, it is more beneficial to study misbehavior of the nodes and develop light-weighted game-theoretic channel allocation mechanisms. With a mix of theoretical and hands-on information, the brief traces the concepts of game theory, the current state of spectrum allocation in wireless networks and future competition for resources. Thorough yet accessible, the content is ideal for researchers and practitioners working on spectrum redistribution. It is also a helpful resource for researchers and advanced-level students interested in game theory and wireless communications.

This thesis documents almost twenty years of the author's work on the development and implementation of a new approach to holistic community development in remote and disadvantaged villages in Nepal. It describes the theoretical basis of the work, the main research activities, and the practical outcomes of the implemented programs. One of the fundamental cornerstones of holistic community development is the provision of appropriate and sustainable solutions for the long-term development of local communities. This requires that people's own identified needs be recognized and addressed in partnership with them in holistic ways. The author explains the many synergies that result from this holistic approach to community development. Another cornerstone of his approach is to utilise the communities' locally available renewable resources for long-term sustainable development. One of the key findings of the thesis is that improved access to energy services, such as cooking with a smokeless metal stove in a clean indoor environment, basic indoor lighting, and increased food production and safe food storage (through a greenhouse and a solar drier respectively), need to be at the very heart of any long-term holistic community development project. The thesis demonstrates that tapping into locally available renewable energy resources and converting them, through contextualized and locally manufactured renewable energy technologies, has a central role in long-term holistic community development programs. Such programs are successful because they provide both appropriate technologies and life-changing experiences for the local users involved.

This SpringerBrief focuses on the network capacity analysis of VANETs, a key topic as fundamental guidance on design and deployment of VANETs is very limited. Moreover, unique characteristics of VANETs impose distinguished challenges on such an investigation. This SpringerBrief first introduces capacity scaling laws for wireless networks and briefly reviews the prior arts in deriving the capacity of VANETs. It then studies the unicast capacity considering the socialized mobility model of VANETs. With vehicles communicating based on a two-hop relaying scheme, the unicast capacity bound is derived and can be applied to predict the throughput of real-world scenarios of VANETs. The downlink capacity of VANETs is also investigated in which access infrastructure is deployed to provide pervasive Internet access to vehicles. Different alternatives of wireless access infrastructure are considered. A lower bound of downlink capacity is derived for each type of access infrastructure. The last section of this book presents a case study based on a perfect city grid to examine the capacity-cost trade-offs of different deployments since the deployment costs of different access infrastructure are highly variable.
