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

    Author : Carl Johan Wallnerström; Lina Bertling; Roland Eriksson; Kjell Sand; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Load and Risk Based Maintenance Management of Wind Turbines

    Author : Pramod Bangalore; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; wind energy.; supervisory control and data acquisition SCADA ; condition monitoring system CMS ; Artificial neural networks ANN ; maintenance strategy; maintenance planning; maintenance management; life cycle cost;

    Abstract : The cost of maintenance is a considerable part of the total life cycle cost in wind turbines, especially for offshore applications. Research has shown that some critical components account for most of the downtime in the wind turbines. READ MORE

  5. 3. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment

    Author : Per Westerlund; Patrik Hilber; Tommie Lindquist; William Q Meeker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; maintenance; condition monitoring; disconnector; circuit breaker; Weibull distribution; prediction; risk analysis; decision making; beta distribution; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. READ MORE

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

    Author : Carl Johan Wallnerström; Rajeev Thottappillil; Patrik Hilber; Ulf Sandberg; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Electricity Distribution Network Planning Considering Distributed Generation

    Author : Yalin Huang; Lennart Söder; Karin Alvehag; Peiyuan Chen; KTH; []
    Keywords : Electricity distribution network; network planning; distributed generation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution.
