   Author : Janko Katic; Ana Rusu; Saul Rodriguez; Gabriel Rincón-Mora; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting interface; thermoelectric generator; glucose biofuel cell; power management; dc-dc converter; boost converter; zero-current switching; zero-voltage switching; implantable biosensor; Energiskördsgränssnitt; termoelektrisk generator; glukosbiobränslecell; energihantering; DC-DC-omvandlare; boost-omvandlare; inplanterbar biosensor; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Energy harvesting is identified as an alternative solution for powering implantable biosensors. It can potentially enable the development of self-powered implants if the harvested energy is properly handled. This development implies that batteries, which impose many limitations, are replaced by miniature harvesting devices. READ MORE

5. 3. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage

   Author : Hailian Xie; Hans-Peter Nee; Lennart Ängquist; Timothy Green; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; Voltage source converter; VSC; Static synchronous compensation; StatCom; Active power compensation; Phase jump; Voltage dip; Weak network; Flux modulation; Deadbeat current control; Transformer saturation; Dual thyristor converter; dc interface; Electrical engineering; Elektroteknik; Electric power engineering; Elkraftteknik;

   Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE

6. 4. Characterization of Different Interface Types for HVDC Extruded Cable Applications

   Author : Espen Doedens; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer surfaces; cable peelings; HVDC; Roughness; Charge injection; XLPE; Field enhancement factors; Schottky injection; DC breakdown; Voltage decay; interfaces; Fowler-Nordheim injection; extruded cable; Roughness assisted charge injection.; Charge decay;

   Abstract : In extruded HVDC cable systems a variety of interface types can be found, and the interfacial properties depend on the application within the system. Such applications can be joints, terminations or the cable itself and they will all have different material combinations and manufacturing methods. READ MORE

7. 5. DC Distributed Power Systems - Analysis, Design and Control for a Renewable Energy System

   Author : Per Karlsson; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; fault detection; load sharing; wind power; DC distributed power system; voltage control; Energy research; Elektronik och elektroteknik; VSC; Electronics and Electrical technology;

   Abstract : Renewable energy systems are likely to become wide spread in the future due to environmental demands. As a consequence of the dispersed nature of renewable energy systems, this implies that there will be a distributed generation of electric power. READ MORE
