An interdisciplinary guided tour of an urban testbed

By: Jens Bley,Kay Hartkopf,Martin Niggemann,Anais Wiedenhöfer

SmartSquare - an interdisciplinary guided tour of an urban testbed SmartSquare is an urban testbed in the emerging domain of “Smart Culture in Smart Cities”. The square is the so-called Domplatz (Cathedral Square), the location of the founding fortification Hammaburg, in the inner city of Hamburg, Germany. SmartSquare is a “Smart Service City” project with multiple-stakeholder perspectives on the activation of this culturally significant inner-city square by means of digital cultural storytelling, data analytics, simulation and service innovation. SmartSquare is a joint project of HafenCity University and the Archaeological Museum Hamburg in cooperation with the digital cluster Hamburg@Work. Funded by the German Federal Ministry for Education and Research (BMBF).

German Expansionism, Imperial Liberalism and the United States, 1776–1945

By: Jens-Uwe Guettel

This book traces the importance of the United States for German colonialism from the late eighteenth century to 1945, focusing on American westward expansion and racial politics. Jens-Uwe Guettel argues that from the late eighteenth century onward, ideas of colonial expansion played a very important role in liberal, enlightened and progressive circles in Germany, which, in turn, looked across the Atlantic to the liberal-democratic United States for inspiration and concrete examples. Yet following a pre-1914 peak of liberal political influence on the administration and governance of Germany's colonies, the expansionist ideas embraced by Germany's far-right after the country's defeat in the First World War had little or no connection with the German Empire's liberal imperialist tradition - for example, Nazi plans for the settlement of conquered Eastern European territories were not directly linked to pre-1914 transatlantic exchanges concerning race and expansionism.

Modeling of Wind Turbines with Doubly Fed Generator System

By: Jens Fortmann

Jens Fortmann describes the deduction of models for the grid integration of variable speed wind turbines and the reactive power control design of wind plants. The modeling part is intended as background to understand the theory, capabilities and limitations of the generic doubly fed generator and full converter wind turbine models described in the IEC 61400-27-1 and as 2nd generation WECC models that are used as standard library models of wind turbines for grid simulation software. Focus of the reactive power control part is a deduction of the origin and theory behind the reactive current requirements during faults found in almost all modern grid codes. Based on this analysis, the design of a reactive power control system for wind turbines and wind plants is deduced that can provide static and dynamic capabilities to ensure a stable voltage and reactive power control for future grids without remaining synchronous generation.

Raw Materials for Future Energy Supply

By: Friedrich-W. Wellmer,Peter Buchholz,Jens Gutzmer,Christian Hagelüken,Peter Herzig,Ralf Littke,Rudolf K. Thauer

This is the first book that analyses the future raw materials supply from the demand side of a society that chiefly relies on renewable energies, which is of great significance for us all. It addresses primary and secondary resources and substitution, not only from technical but also socioeconomic and ethical points of view. The “Energiewende” (Energy Transition) will change our consumption of natural resources significantly. When in future our energy requirements will be covered mostly by wind, solar power and biomass, we will need less coal, oil and natural gas. However, the consumption of minerals, especially metallic resources, will increase to build wind generators, solar panels or energy storage facilities. Besides e.g. copper, nickel or cobalt, rare earth elements and other high-tech elements will be increasingly used. With regard to primary metals, Germany is 100 % import dependent; only secondary material is produced within Germany. Though sufficient geological primary resources exist worldwide, their availability on the market is crucial. The future supply of the market is dependent on the development of prices, the transparency of the market and the question of social and ethical standards in the raw materials industry, as well as the social license to operate, which especially applies to mining. The book offers a valuable resource for everyone interested in the future raw material supply of our way of life, which will involve more and more renewable energies.
