   Sammanfattning : The global energy system is experiencing a transition to a sustainable system with ambitious targets for increased use of renewable energy. One key trend for this transition has been the large introduction of wind power and integration into the electricity grid. LÄS MER

3. 22. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

   Författare :Ingmar Leisse; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

   Sammanfattning : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. LÄS MER

4. 23. Integration of Wind Power in Medium Voltage Networks - Voltage Control and Losses

   Författare :Ingmar Leisse; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Since some years ago greenhouse gases and especially carbon dioxide have become one of the most widely debated issues. To reduce the emission of carbon dioxide and nuclear waste, renewable energy sources as for example wind power plants have become very successful. LÄS MER

5. 24. Active Distributed Power Systems Functional Structures for Real-Time Operation of Sustainable Energy Systems

   Författare :Jörgen Svensson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Distributed power systems; RES; Power electronics; Energy management system; Real-time operation; Advanced functions; Communication; Elektronik och elektroteknik; Electronics and Electrical technology; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems. LÄS MER

7. 25. Grid Integration and Impact of a Wave Power System

   Författare :Arvind Parwal; Cecilia Boström; Damir Šljivac; Uppsala universitet; []
