Preface First of all I wish to express my deepest gratitude to my advisor Dr. Rainer Bacher for introducing me to the worlds of software engineering and power system optimization. The motivating remarks and valuable suggestions, his positive attitude, and his encouragement and patience have been a big help for me over the last four years. Further, I would(More)
A concept for the automatic generation of optimization code for a class of non-linear optimization problems is described and realized at the example of an electric power system optimal power flow problem. The equations are structured based on a node and edge structure given from a network. The goal of this domain engineering approach is the high-level(More)
Four approximate sparse vector (SV) techniques to speed up power network computer applications are described. Three are approximations of established SV techniques. Skip forward is an approximation of fast forward, skip back is an approximation of fast back, and skip factor update is an approximation of factor update. Skip back by columns (SBC), an entirely(More)
The Global Accelerator Network (GAN) is a proposed model to design, build, operate and maintain a future large accelerator by partners of an international collaboration. This novel approach has many legal, sociological and technical issues. This paper will describe the general ideas of the GAN model and report on first results of a workshop series recently(More)
GridBox is an open platform for monitoring and active control of distribution grids. It is based on an innovative concept that comprehensively addresses the challenges DSOs will be exposed to in the context of increasing amount of decentralized and often fluctuating generation as well as the electrification of the heat and transportation sector. In this(More)
] suggested a radiochemical method using a fission reactor based on the reaction v + 37C1-37Ar + e-. They did not pursue the method. Alvarez was dissuaded by his estimates of the background to be anticipated from cosmic rays; these estimates later proved to be correct for the reactors then available. As we know now, the neutrino produced in fission is be(More)
Back cover: Electrical field simulation in a two-dimensional representation of the switching chamber of a generator circuit breaker. Field strength is depicted by color, where blue corresponds to low strength and red high strength. The simulation is designed to gather information relevant to the placement of electric field probes exterior to the breaker(More)
