2. 1. On Techno-economic Assessment of a Multi-terminal VSC-HVDC in AC Transmission Systems

   Author : Feng Wang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission Grid.; Loss minimization; AC DC system; Transmission expansion planning; Multi-terminal VSC-HVDC; Cost minimization; Cost-benefit analysis; Electric power system; Optimal power flow;

   Abstract : The Voltage Source Converter based Multi-Terminal high voltage Direct Current transmission system (VSC-MTDC) is currently considered as an attractive technical option for increased transmission capacity and improved controllability and flexibility of an electric power grid, thanks to its unique performance characteristics, and the possibility of using the extruded XLPE cables. In the planning process of embedding a VSC-MTDC system into an ac transmission grid, one must assess the potential values in terms of improved energy efficiency, i. READ MORE

4. 2. Data Driven Condition Monitoring for Transmission and Axles

   Author : Elisabeth Källström; John Lindström; Magnus Karlberg; Jiri Tuma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. READ MORE

5. 3. 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

6. 4. Integration of the Nordic electricity grids : incentives, cost sharing and regional perspective in transmission investments

   Author : Hans Nylund; Thomas Tangerås; Luleå tekniska universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Abstract : The overall purpose of this thesis is to study how the development of the electricity transmission grids in the Nordic countries can be given a stronger international perspective. This is a relevant issue for the further development of the regional Nordic electricity market. READ MORE

7. 5. Marginal cost pricing of electricity

   Author : Göran Edsbäcker; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : The discipline is economics and the phenomenon is the power system. The purpose of this system is to produce, transmit and consume electricity in such a way that the sum of consumers' and suppliers' surplus is maximized. This is accomplished by the means of marginal cost pricing. READ MORE
