2. 21. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

   Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

4. 22. On performance limitations of large-scale networks with distributed feedback control

   Author : Emma Tegling; Henrik Sandberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. READ MORE

5. 23. Large-scale agile transformation in a manufacturing company : a knowledge-based view

   Author : Silvia Orejuela; Innovation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large-scale agile; Organisational transformation; Knowledge specialisation; Knowledge boundaries; Knowledge integration; Manufacturing company;

   Abstract : Agile has been touted as a concept to deal with and succeed in the fast-paced environment in which companies operate today. Based on this concept, practitioners have created frameworks and practices that have proven to bring benefits in software development. READ MORE

6. 24. Understanding and supporting large-scale requirements management

   Author : Krzysztof Wnuk; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; release planning; requirements engineering;

   Abstract : Large market-driven software companies face new challenges in requirements engineering and management that emerged due to their recent extensive growth. At the same time, the pressure generated by competitors’ and users’ expectations demands being more competitive, creative and flexible to more quickly respond to a rapidly changing market situation.

7. 25. Continuous Management of Artifacts and Traceability in Large-Scale Agile Systems Engineering

   Author : Rebekka Wohlrab; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Traceability Management; Large-Scale Agile Development; Empirical Research; Automotive; Systems Engineering; Requirements Engineering;

   Abstract : Context: In large-scale systems engineering, a large number of requirements, models, and other artifacts is created, used, and maintained by many stakeholders. When adopting agile methods and trying to reduce unnecessary documentation, companies need to reevaluate how to manage both artifacts and traceability between them. READ MORE
