2. 11. 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.

4. 12. A Novel Method for Adaptive Control of Manufacturing Equipment in Cloud Environments

   Author : Göran Adamson; Philip Moore; Lihui Wang; Robert Harrison; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Function Block; Adaptive control; Robot-Control-as-a-Service; Cloud Manufacturing; Production and Automation Engineering; Produktion och automatiseringsteknik;

   Abstract : The ability to adaptively control manufacturing equipment, both in local and distributed environments, is becoming increasingly more important for many manufacturing companies.One important reason for this is that manufacturing companies are facing increasing levels of changes, variations and uncertainty, caused by both internal and external factors, which can negatively impact their performance.

6. 14. The Impact of High-Quality Information on Performance in Manufacturing

   Author : Roger Lindau; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time; automatic data capture; planning; disturbances; high-quality information; manufacturing; disturbance absorption measures; scheduling;

   Abstract : The dissertation deals with the impact of high-quality information on performance in manufacturing. In a system where two material flows with sequence dependency are matched, the use of real-time information to monitor and control the sequencing buffer improves the system's ability to schedule many different models, compared with a system with no information at all.
