  1. 1. Assessment of Interruption Costs in Electric Power Systems using the Weibull-Markov Mode

    Författare :Jasper van Casteren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semi-Markov model; interruption cost; power system reliability; customer damage function; duration distribution; reliability worth;

    Sammanfattning : Modern competitive electricity markets do not ask for power systems with the highest possible technical perfection, but for systems with the highest possible economic efficiency. Higher efficiency can only be reached when accurate and flexible analysis tools are used. LÄS MER

  3. 2. Risk-based methods for reliability investments in electric power distribution systems

    Författare :Karin Alvehag; Lennart Söder; Kjølle Gerd; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distribution system reliability; risk management; quality regulation design; customer interruption costs; weather modeling; Monte Carlo simulations; Electric power engineering; Elkraftteknik;

    Sammanfattning : Society relies more and more on a continuous supply of electricity. However, while underinvestments in reliability lead to an unacceptable number of power interruptions, overinvestments result in too high costs for society. LÄS MER

  4. 3. Maintenance optimization for power distribution systems

    Författare :Patrik Hilber; Lina Bertling; Roland Eriksson; Lalit Goel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability Importance Index; Multiobjective Optimization; Maintenance Optimization; Asset Management; Customer Interruption Cost; Reliability Centred Maintenance RCM ; Reliability Centered Asset Management RCAM ; Monte Carlo Simulation; Evolutionary Particle Swarm Optimization.; Electric power engineering; Elkraftteknik;

    Sammanfattning : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. LÄS MER

  5. 4. An analysis of factors influencing renewable energy deployment in the EU’s electricity sector

    Författare :Abhishek Shivakumar; Mark I. Howells; Mikael Höök; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable energy; energy storage; interruption costs; long-term energy models; cross-border interconnectors; European Union;

    Sammanfattning : The EU has set itself ambitious short- and long-term decarbonisation targets: a reduction in greenhouse gas (GHG) emissions of 40% by 2030 and 80% by 2050, compared to 1990 levels. The power generation sector, currently responsible for around 55% of GHG emissions, is expected to contribute significantly to achieving the EU’s decarbonisation targets. LÄS MER

  7. 5. Impact of dependencies in risk assessments of power distribution systems

    Författare :Karin Alvehag; Lennart Söder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning :  Society has become increasingly dependent on electricity, so power system reliability is of crucial importance. However, while underinvestment leads to an unacceptable number of power outages, overinvestment will result in costs that are too high for society. The challenge is to find a socioeconomically adequate level of risk. LÄS MER
