1. 1. Quantitative vulnerability analysis of electric power networks

   Författare :Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
   Nyckelord :Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. LÄS MER

3. 2. On Risk Management of Electrical Distribution Systems and the Impact of Regulations

   Författare :Carl Johan Wallnerström; Lina Bertling; Roland Eriksson; Kjell Sand; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Distribution System; Maintenance Management; Project Planning; Regulation; Reliability Analysis; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Risk Analysis; Risk Management; Risk Methods; the Network Performance Assessment Model NPAM ; Electric power engineering; Elkraftteknik;

   Sammanfattning : The Swedish electricity market was de-regulated in 1996, followed by new laws and a new regulation applied to the natural monopolies of electrical distribution systems (EDS). These circumstances have motivated distribution systems operators (DSOs) to introduce more comprehensive analysis methods. LÄS MER

4. 3. On Incentives affecting Risk and Asset Management of Power Distribution

   Författare :Carl Johan Wallnerström; Rajeev Thottappillil; Patrik Hilber; Ulf Sandberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; correlation studies; incentives; investment planning; maintenance planning; power distribution; reliability analysis; risk management; statistical validation; tariff regulation; vulnerability analysis; weather states; Electric power engineering; Elkraftteknik; Mathematical statistics; Matematisk statistik; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. LÄS MER

5. 4. Learning for safety in health care and air traffic control

   Författare :Sven Ternov; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Risk management; accident models; complex systems; health care; air traffic control; MTO analysis; DEB-analysis; proactive risk analysis.;

   Sammanfattning : Introduction Risk management in enterprises, organisations and companies has had a long and complicated history. During the eighties, and at least during the beginning of the nineties, the notion concerning risk management was that if an accident happened in an otherwise perfect system it was due to the human operator in some way being the cause of the error.

7. 5. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

   Författare :Johan Setréus; Lina Bertling; Roland Eriksson; Stefan Arnborg; Lars Wredenberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; Electric power engineering; Elkraftteknik;

   Sammanfattning : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. LÄS MER
