1. 16. Impact of High Levels of Variable Renewable Energy on Power System Generation Adequacy : Methods for analyzing and ensuring the generation adequacy of modern, multi-area power systems

   Författare :Egill Tomasson; Lennart Söder; Dirk Van Hertem; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generation adequacy; reliability; renewable energy; Monte Carlo simulation; electricity markets; optimization; mathematical programming; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The generation adequacy of electricity supply has been an ongoing concern since the restructuring of the industry. Ensuring generation adequacy was a rather straightforward task in the era of natural monopolies. LÄS MER

3. 17. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance

   Författare :Tommie Lindquist; Prof. Roland Eriksson; Dr. Lina Bertling; Docent Carl-Ejnar Sölver; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Maintenance; reliability modelling; electrical power systems; ageing; failure mechanisms; Elkraftteknik; Electric power engineering; Elkraftteknik;

   Sammanfattning : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. LÄS MER

4. 18. Active Distributed Power Systems Functional Structures for Real-Time Operation of Sustainable Energy Systems

   Författare :Jörgen Svensson; Industriell elektroteknik och automation; []

   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

5. 19. Systems Dependability Engineering for Wind Power Applications : Challenges, Concepts, and System-Level Methodologies

   Författare :Idriss El-Thalji; Anders Karlsson; Linnéuniversitetet; []
   Nyckelord :System Dependability; Systems Engineering; Terotechnology; Terotechnology; Systemekonomi;

   Sammanfattning : Complexity and uncertainty have impacted wind power systems and their applications.Commercial wind power asset exhibits complex system behaviour due tostochastic loading characteristics of its installation context. However, differentstakeholders’ practices in whole life cycle processes try to treat multi-disciplinarycomplexity issues. LÄS MER

7. 20. Reliability-based Assessment of Concrete Dam Stability

   Författare :Marie Westberg; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

   Sammanfattning : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. LÄS MER
