2. 6. Frequency response by wind farms in power systems with high wind power penetration

   Author : Mattias Persson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inertia estimation; frequency control; power system stability; wind power integration; Power system; synthetic inertia;

   Abstract : The integration of variable speed wind turbines (VSWT) in power systems is increasing in order to reduce the emission of green house gases. This increase of power electronic converter interfaced generation causes a decrease of power system inertia, increasing the risk of load shedding and system frequency instability. READ MORE

4. 7. Climate Change Leadership - the case for Electrification

   Author : Per Ribbing; Mats Leijon; Tomas Kåberger; Uppsala universitet; []
   Keywords : Green Power; Consumer Power; Renewable Energy; Energy efficiency; Paradigm shift; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : This licentiate thesis presents a new way of understanding Electric Power. The new perspective on Electric Power highlights the similarities between our banking system and our power system. The two different systems share a common abstraction. In the case of the banking system this abstraction is fully accepted. READ MORE

5. 8. Towards Green Wireless Access Networks : Main Tradeoffs, Deployment Strategies and Measurement Methodologies

   Author : Sibel Tombaz; Jens Zander; Ki Won Sung; Ben Slimane; Peter Legg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; wireless access; green radio; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Wireless access networks today consume 0.5 percent of the global energy. Rapidly growing demand for capacity will further increase the energy consumption. Thus, improving energy efficiency has a great importance not only for environmental awareness but also to lower the operational cost of network operators. READ MORE

6. 9. Cooperative Communications : Link Reliability and Power Efficiency

   Author : Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. READ MORE

7. 10. Supportability Engineering in Wind Power Systems - Who Cares? : Considering important stakeholders and their requirements

   Author : Renato Ciganovic; Per Anders Akersten; Marcus Bengtsson; Linnéuniversitetet; []
   Keywords : Supportability; Supportability Engineering; Stakeholders Requirements; Non-functional Requirements; Integrated Logistic Support; Asset Management; Maintenance Support; Logistic Support; Wind Energy; Wind Power; Accessibility; Maintainability; Serviceability; Supported System; Terotechnology; Systemekonomi;

   Abstract : Wind power is one of the fastest growing energy sources, which have advantages in terms of delivering clean, cheap and fast energy. Many actors and organizations have realized this potential, which has lead to exponential growth of the wind power over recent couple of years. READ MORE
