1. 6. On Optimization Based Control of Distributed Energy Resources in Power Systems: Electricity Markets and Voltage Regulation Perspectives

   Författare :Pavan Balram; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model predictive control and distribution systems; Electric vehicles; electricity markets; coordinated voltage control; battery energy storage; photovoltaics;

   Sammanfattning : Distributed energy resources are increasingly being integrated into power systems around the world. These resources, typically connected at the distribution system level, are already changing the pattern of power flow from being unidirectional to multidirectional. LÄS MER

3. 7. Increasing the hosting capacity of distributed energy resources using storage and communication

   Författare :Nicholas Etherden; Joao A Peças Lopes; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Systems; Renewable Energy; Energy Storage; Hosting Capacity; Curtailment; Power Utility Automation; IEC 61850; Smart Grid; Elkraft; Förnyelsebara energikällor; Energilager; Acceptansgräns; Produktionsnedstyrning; Kraftsystemsautomation; IEC 61850; Smarta elnät; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : This thesis develops methods to increase the amount of renewable energy sources that can be integrated into a power grid. The assessed methods include i) dynamic real-time assessment to enable the grid to be operated closer to its design limits; ii) energy storage and iii) coordinated control of distributed production units.

4. 8. A co-simulation based framework for the analysis of integrated urban energy systems : Lessons from a Swedish case study

   Författare :Monica Arnaudo; Björn Laumert; Monika Topel; Louise Ödlund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Sammanfattning : As major responsible for CO2 emissions, the energy sector is urgently called to take action against climatechange. The integration of renewable energy resources is a solution that, however, comes with a challenge.In fact, renewables are often variable, unpredictable and distributed. LÄS MER

5. 9. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter

   Författare :Jens Engström; Jan Isberg; Mats Leijon; Antonio Sarmento; Uppsala universitet; []
