  2. 1. Submerged Transmission in Wave Energy Converters : Full Scale In-Situ Experimental Measurements

    Author : Erland Strömstedt; Mats Leijon; Hans Bernhoff; Jan-Olov Aidanpää; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy converter; direct drive; submerged transmission; piston rod; seal housing; sealing system; laser triangulation sensor; offshore measurements; relative displacement; vibrations; tilt angle; tilting; wear estimation.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. READ MORE

  4. 2. Variation management for cost-efficient integration of variable renewable electricity

    Author : Viktor Walter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility measures; Energy storage; Energy system modelling; Renewable Energy;

    Abstract : The aim of this work is to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the electricity system in a cost-efficient manner. For this, a techno-economic cost-minimising model of the electricity system is used for a set of case studies. READ MORE

  5. 3. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments

    Author : Elof Köhler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; coupled harvester; Thermoelectric; harsh environment; piezoelectric harvester; Energy harvester; supercapacitor; Thermoelectric harvester;

    Abstract : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. READ MORE

  6. 4. On Sustainability in Local Energy Planning

    Author : Farhad Derakhshan; Energihushållning; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Indicators; Sustainable Development; Energy Systems; Energy Planning;

    Abstract : Energy is among the main driving forces needed for sustainable development. Provision of energy services, from the supply side to transmission/distribution and use, must include management, and good management requires tools. Energy planning is a tool for managing the community energy system through assessing and balancing supply and demand. READ MORE

  7. 5. Future District Heating Interactions – Modelling Impacts of Industrial Excess Heat Utilisation and Energy Efficient Buildings

    Author : Akram Sandvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fourth generation district heating; TIMES; waste heat; urban planning.; dynamic energy system modelling; MARKAL; passive houses; low-energy buildings; excess heat;

    Abstract : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. READ MORE
