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. Maximizing the integration of wind power in distribution system

   Author : Shemsedin Nursebo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distribution system; integration issues of wind power; cost benefit analysis.; frequency of tap change; active management strategies;

   Abstract : The global installed capacity of wind power has shown a significant growth, from just 24 GW in 2001 to 283 GW in 2012. This trend is expected to continue for some years to come. Hence a significant amount of wind power needs to be connected to the electric power system. READ MORE

5. 3. Data Quality in Wide-Area Monitoring and Control Systems : PMU Data Latency, Completness, and Design of Wide-Area Damping Systems

   Author : Kun Zhu; Lars Nordström; Boming Zhang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor Measurement Units; Wide-Area Monitoring and Control systems; latency; completeness; power system communication; simulation; empirical study;

   Abstract : The strain on modern electrical power system operation has led to an ever increasing utilization of new Information Communication Technology (ICT) systems to enhance the reliability and efficiency of grid operation. Among these proposals, Phasor Measurement Unit (PMU)-based Wide-Area Monitoring and Control (WAMC) systems have been recognized as one of the enablers of “Smart Grid”, particularly at the transmission level, due to their capability to improve the real-time situational awareness of the grid.

6. 4. Multi-Threaded Distributed System Simulations : Using Bi-Lateral Delay Lines

   Author : Robert Braun; Petter Krus; Asko Ellman; Linköpings universitet; []
   Keywords : ;

   Abstract : As the speed increase of single-core processors keeps declining, it is important to adapt simulation software to take advantage of multi-core technology. There is a great need for simulating large-scale systems with good performance. READ MORE

7. 5. Exploiting Energy Awareness in Mobile Communication

   Author : Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Daniele Puccinelli; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless transmission energy; energy consumption; mobile devices; power measurements; application energy; data pattern; trace-based simulation;

   Abstract : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.
