1. 1. Security of Electricity Supply in Power Systems : Establishing a Global Framework for Assessing Power System Health and Analyzing Outage Statistics in Sweden

   Författare :Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; Christina Papadimitriou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security of electricity supply; power system health; outage statistics; data analysis; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The primary objective of this thesis is to enhance the security of electricity supply by providing a holistic perspective and introducing a comprehensive framework for assessing power system health. This novel approach aims for a thorough evaluation of the system’s overall performance and well-being, using the physical dimensions of the security of supply as the foundation for a power system health index.

4. 3. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning

   Författare :Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; George Anders; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The importance of electricity in everyday life and demands to improve the reliability of distribution systems force utilities to operate and plan their networks in a more secure and economical manner. With higher demands on reliability from both customers and regulators, a big pressure has been put on the security of electricity supply which is considered as a fundamental requirement for modern societies.

5. 4. The roles of transmission and distribution networks in integrating variable renewable electricity generation

   Författare :Joel Goop; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity generation; demand-side management; energy systems modelling; power systems; variable renewables;

   Sammanfattning : Emission reduction targets, together with other factors, such as security of supply, are driving the expansion of variable renewable energy sources for electricity generation, mainly solar and wind power. Trading across the transmission grid is an important measure to handle the increased variability and to balance supply with demand. LÄS MER

7. 5. A trinity of sense : Using biomass in the transport sector for climate change mitigation

   Författare :Erik G. Lindfeldt; Mats Westermark; Lars J. Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuel; biomass; carbon dioxide capture and storage; energy systems; ethanol; hybrid cycle; mixed conducting membrane reactor; pressurized fluidized bed combustion; Sweden; transport; Chemical engineering; Kemiteknik;

   Sammanfattning : This thesis analyses two strategies for decreasing anthropogenic carbon dioxide (CO2) emissions: to capture and store CO2, and to increase the use of biomass. First, two concepts for CO2 capture with low capture penalties are evaluated. LÄS MER
