Assessment of a cellular structure in an indoor environment using models extracted from measurements at 1.9G Hz in the Electrical Engineering department of the Delft University of Technology

The cell size and cluster structure are evaluated using an outage probability model which is based on the measurements at the 19th floor of the faculty of Electrical Engineering, TU-Delft. An analytical expression for the relationship between the Rice factor and the multipath component is derived. This expression is checked using the Kolmogorov-Smirnov best fit test. Outage probability calculations are done in case of multiple Rician and multiple Rayleigh interference without shadow fading. It is shown that the outage probability calculation based on Rayleigh interferers with different local mean power corresponds best to the measured signal behaviour.Applied SciencesElectrical EngineeringTelecommunications and Traffic-Control Systems Grou

A hydrogen-based integrated energy and transport system: The design and analysis of the Car as Power Plant Concept

In recent years, the European Union (EU) has set ambitious targets toward a carbon-free energy transition. Many studies show that a drastic reduction in greenhouse gas emissions-at least 90% by 2050-is required. In the transition toward a sustainable energy system, solar (or green) hydrogen plays many important roles, as it is a clean and safe energy carrier that can also be used as a fuel in transportation and in electricity production. To understand and steer the transition from the current energy system toward an integrated hydrogenbased energy and transport system, we propose a framework that integrates a technical and economic feasibility study, a controllability study, and institutional analysis. This framework is applied to the Car as Power Plant (CaPP) concept, which is an integrated energy and transport system. Such a system consists of a power system based on wind and solar power, conversion of renewable energy surpluses to hydrogen using electrolysis, hydrogen storage and distribution, and hydrogen fuel cell vehicles that provide mobility, electricity, heat, and water. Controlling these vehicles in their different roles and designing an appropriate organizational system structure are necessary steps in the feasibility study. Our proposed framework for a future 100% renewable energy system is presented through a case study.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Energy & IndustryEnergy TechnologyTeam DeSchutterDelft Center for Systems and Contro
