Download or read book Grid Systems written by Kimberly Elam and published by Chronicle Books. This book was released on 2014-04-15 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although grid systems are the foundation for almost all typographic design, they are often associated with rigid, formulaic solutions. However, the belief that all great design is nonetheless based on grid systems (even if only subverted ones) suggests that few designers truly understand the complexities and potential riches of grid composition.

Available in PDF, EPUB and Kindle. Book excerpt: The book is the first to define the meaning and components of the grid and apply it in Chinese planning history. It provides a fresh methodology, pushing the boundary of planning by this new practical tool for planners and governors and new perspective for the architecture and city planning faculties. From graphs to rules, from facts to in-depth analysis, this book focuses on the tool of urban planning, the grid, with thoughtful organization of knowledge from Chinese history, architecture and city planning discipline, providing knowledge along with politics, military, customs, mysterious Fengshui theories and astrology beliefs. Moreover, the book proved the link between grids and social aims, discussing each kind of aim by thoughtful organization of data collected from 301 prefecture cities, unfolding the powers propelling the city formation and shedding light on what shaped our cities today.

Download or read book A Comprehensive Approach to Implement Monitoring and State Estimation in Distribution Grids with a Low Number of Measurements written by Jan-Hendrik Menke and published by BoD – Books on Demand. This book was released on 2020-01-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work addresses the monitoring and state estimation of electrical grids, especially at the distribution level. For economic and technical reasons, grid monitoring cannot be implemented with a similarly high measurement density as in transmission grids. Two new monitoring methods, which are designed for low measurement density, are therefore presented for use in real-time grid operation. First, a heuristic monitoring method is presented, which does not require pseudo-measurements and estimates voltage magnitudes and line loadings. Second, a monitoring method based on artificial neural networks is presented. With appropriate training, the method can estimate grid variables, e.g., voltage magnitudes or line loadings, with high accuracy. The methods are tested on thousands of test scenarios using a comprehensive evaluation methodology. For measurement infrastructure planning, a concept is presented to determine suitable measurement locations for the use of one of the monitoring methods. After optimization, several possible measurement configurations are presented with their average and maximum errors and the projected capital expenditures.

Download or read book Multi terminal Direct Current Grids written by Nilanjan Chaudhuri and published by John Wiley & Sons. This book was released on 2014-09-09 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A generic DC grid model that is compatible with the standard AC system stability model is presented and used to analyse the interaction between the DC grid and the host AC systems. A multi-terminal DC (MTDC) grid interconnecting multiple AC systems and offshore energy sources (e.g. wind farms) across the nations and continents would allow effective sharing of intermittent renewable resources and open market operation for secure and cost-effective supply of electricity. However, such DC grids are unprecedented with no operational experience. Despite lots of discussions and specific visions for setting up such MTDC grids particularly in Europe, none has yet been realized in practice due to two major technical barriers: Lack of proper understanding about the interaction between a MTDC grid and the surrounding AC systems. Commercial unavailability of efficient DC side fault current interruption technology for conventional voltage sourced converter systems This book addresses the first issue in details by presenting a comprehensive modeling, analysis and control design framework. Possible methodologies for autonomous power sharing and exchange of frequency support across a MTDC grid and their impact on overall stability is covered. An overview of the state-of-the-art, challenges and on-going research and development initiatives for DC side fault current interruption is also presented.
Download or read book Smart Grids Renewable Energy Power Electronics Signal Processing and Communication Systems Applications written by Alfeu J. Sguarezi Filho and published by Springer Nature. This book was released on 2023-12-23 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses power electronics, signal processing and communication systems applications in smart grids (SG). Smart grids can be considered an evolution of the classic energy model to allow a more efficient management of the relationship between supply and demand, in order to overcome the contingency problems of the modern world. To achieve their goals, they use advanced technologies of information and communication, power electronics and signal processing, and can be used to integrate renewable energy sources. The book is divided into two main parts. The first part presents the application of power electronics technologies in renewable energy systems, while the second part presents some telecommunications, signal processing and energy capture technologies within the context of SGs. The chapters are written by invited expert authors, according to their research areas.
Download or read book Modeling and control of power converters in weak and unbalanced electric grids written by Just, Hendrik and published by Universitätsverlag der TU Berlin. This book was released on 2021-11-25 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grid converters increasingly affect power system operation due to the increasing share of renewable energy sources and less conventional power plants. This shift in power generation leads to converter-dominated weak grids, which show critical stability phenomena but also enable converters to contribute to grid stability and voltage support. This thesis presents critical parts of converter controls and describes models to assess their characteristics. These models are used to derive design criteria and dedicated stability analysis methods for grid converter controls. Der steigende Anteil an erneuerbaren Energien in den Energieversorgungsnetzen führt zur Verdrängung konventioneller Kraftwerke. Diese Entwicklung lässt umrichterdominierte und schwache Netzabschnitte entstehen, die kritischen Stabilitätsmechanismen unterliegen, allerdings auch ermöglichen, dass Umrichter aktiv zur Netzstützung und Netzstabilität beitragen können. Die vorliegende Arbeit beschreibt kritische Regelungskomponenten der Umrichter und deren Modellierung. Auf Basis der Modelle werden Auslegungskriterien für die Regelungen abgeleitet und dedizierte Stabilitätsanalysemethoden präsentiert.
