1. 26. Grid-forming wind power plants

   Författare :Anant Narula; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power plants WPPs ; grid-forming GFM ; inertia; Ancillary services; frequency support; coordination; current limitation; energy storage systems ESS ; transient stability;

   Sammanfattning : With growing concerns over climate change, the power system is witnessing an unprecedented growth in electricity generation from intermittent renewable energy sources (RES) such as wind and solar, which are commonly interfaced to the grid by power-electronic converters. However, increasing the penetration level of converter-interfaced generation units reduces the number of synchronous generators (SGs) in the grid that provide system services to support voltage and frequency, either inherently or through mandatory requirements and market products.

3. 27. The social power grid : The role of institutions for decentralizing the electricity grid

   Författare :Martin Warneryd; Eva Thorin; Tomas Kåberger; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

   Sammanfattning : The world’s existing electricity grids face several challenges if they are to continue to provide a stable supply in the future. Aging electricity grids and the massive implementation of renewable sources require a different flexibility and robustness of future grids. LÄS MER

4. 28. The role of Swedish single-family dwellings in the electricity system - The importance and impacts of solar photovoltaics, demand response, and energy storage

   Författare :Emil Nyholm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electricity system models; Electric space heating; Batteries; Demand response; Single-family dwellings; Demand side management; Optimization; Solar photovoltaics; Distributed generation;

   Sammanfattning : This thesis investigates the role Swedish single-family dwellings can play in the electricity system. Both through becoming electricity producers through the use of solar photovoltaic (PV) systems, and the possibilities of demand response (DR) and energy storage in combination with this, and through the DR of electric space heating in the dwellings.

5. 29. 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. 30. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER
