Book Synopsis Evaluating Demand Response Opportunities for Data Centers by : Sonja Klingert
Download or read book Evaluating Demand Response Opportunities for Data Centers written by Sonja Klingert and published by Cuvillier Verlag. This book was released on 2020-12-03 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data center demand response is a solution to a problem that is just recently emerging: Today’s energy system is undergoing major transformations due to the increasing shares of intermittent renewable power sources as solar and wind. As the power grid physically requires balancing power feed-in and power draw at all times, traditionally, power generation plants with short ramp-up times were activated to avoid grid imbalances. Additionally, so-called demand response schemes may incentivize power consumers to manipulate their planned power profile in order to activate hidden sources of flexibility. The data center industry has been identified as a suitable candidate for demand response as it is continuously growing and relies on highly automated processes. The presented thesis exceeds the related work by creating a framework for modeling data center demand response on a high level of abstraction that allows subsuming a great variety of specific models. Based on a generic architecture of demand response enabled data centers this is formalized through a micro-economics inspired optimization framework that generates technical power flex functions and an associated cost and market skeleton. This is evaluated through a simulation based on 2014 data from a real HPC data center in Germany, implementing two power management strategies, namely temporal workload shifting and manipulating the CPU frequency. The flexibility extracted is then monetized on two German electricity markets. As a result, in 2014 this data center would have achieved the largest benefit by changing from static electricity pricing to dynamic EPEX prices without changing their power profile. Through demand response they might have created an additional gross benefit of 4% of the power bill on the secondary reserve market. In a sensitivity analysis, however, it could be shown that these results are largely dependent on specific parameters as service level agreements and job heterogeneity. The results show that even though concrete simulations can evaluate demand response activities of individual data centers, the proposed modeling framework helps to understand their relevance from a system-wide viewpoint.
Book Synopsis Bridging Circuits and Fields by : Alexander I. Petroianu
Download or read book Bridging Circuits and Fields written by Alexander I. Petroianu and published by CRC Press. This book was released on 2021-11-30 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy and power are fundamental concepts in electromagnetism and circuit theory, as well as in optics, signal processing, power engineering, electrical machines, and power electronics. However, in crossing the disciplinary borders, we encounter understanding difficulties due to (1) the many possible mathematical representations of the same physical objects, and (2) the many possible physical interpretations of the same mathematical entities. The monograph proposes a quantum and a relativistic approach to electromagnetic power theory that is based on recent advances in physics and mathematics. The book takes a fresh look at old debates related to the significance of the Poynting theorem and the interpretation of reactive power. Reformulated in the mathematical language of geometric algebra, the new expression of electromagnetic power reflects the laws of conservation of energy-momentum in fields and circuits. The monograph offers a mathematically consistent and a physically coherent interpretation of the power concept and of the mechanism of power transmission at the subatomic (mesoscopic) level. The monograph proves (paraphrasing Heaviside) that there is no finality in the development of a vibrant discipline: power theory.
Book Synopsis Field Theory Concepts by : Adolf J. Schwab
Download or read book Field Theory Concepts written by Adolf J. Schwab and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Field Theory Concepts" is a new approach to the teaching and understanding of field theory. Exploiting formal analo- gies of electric, magnetic, and conduction fields and introducing generic concepts results in a transparently structured electomagnetic field theory. Highly illustrative terms alloweasyaccess to the concepts of curl and div which generally are conceptually demanding. Emphasis is placed on the static, quasistatic and dynamic nature of fields. Eventually, numerical field calculation algorithms, e.g. Finite Element method and Monte Carlo method, are presented in a concise yet illustrative manner.

Book excerpt: The way in which our society exists, operates and develops is strongly influenced by the way in which energy is produced and consumed. No process in industry can be performed without a sufficient supply of energy, and without industry there can be no production of commodities, on which the existence of modern society depends. Energy systems have evolved over a long period and more rapidly over the last two centuries, as a response to the requirements of industry and society, starting with the combustion of fuels and building up to the exploitation of nuclear energy and renewable resources. It is clear that the evolution of energy systems is a continuous process, which involves constant technological developments and innovation.This book publishes papers presented at the First International Conference on Energy and Sustainability.

Book Synopsis A Comprehensive Approach to Implement Monitoring and State Estimation in Distribution Grids with a Low Number of Measurements by : Jan-Hendrik Menke
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.
Book Synopsis Distributed Optimization with Application to Power Systems and Control by : Engelmann, Alexander
Download or read book Distributed Optimization with Application to Power Systems and Control written by Engelmann, Alexander and published by KIT Scientific Publishing. This book was released on 2022-11-21 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical optimization techniques are among the most successful tools for controlling technical systems optimally with feasibility guarantees. Yet, they are often centralized—all data has to be collected in one central and computationally powerful entity. Methods from distributed optimization overcome this limitation. Classical approaches, however, are often not applicable due to non-convexities. This work develops one of the first frameworks for distributed non-convex optimization.
Book Synopsis Resilient Operation of Distribution Grids with Distributed-Hierarchical Architecture by : Elisabeth Drayer
Download or read book Resilient Operation of Distribution Grids with Distributed-Hierarchical Architecture written by Elisabeth Drayer and published by kassel university press GmbH. This book was released on 2018-11-20 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is about the design and the implementation of a resilient grid operation for the distribution grid. This research question is induced by the advancing of three trends: Decarbonisation, decentralisation and digitalisation. These three trends transform the hitherto passive distribution grid into an active system that contains an active operation. The term “resilience” describes capabilities of the system to absorb, to adapt, and to recover from faults and disturbances. This concept is realised on the one hand with the choice of the operation architecture, on the other hand for the choice of possible methods and functions. This thesis develops a distributed-hierarchical operation architecture. For this architecture several methods have been developed that optimally benefit from the operation architecture and that allow the fully automated operation of the distribution grid. For that purpose a heuristic optimisation has been developed to solve problems like voltage profile violations and congestions. Another important method, especially with regard to resilience, is the self-healing capability to resupply clients after permanent faults.

This book was released on 2016-12-30 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Modeling and control of power converters in weak and unbalanced electric grids by : Just, Hendrik
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.
