  4. 2. From data collection to electric grid performance : How can data analytics support asset management decisions for an efficient transition toward smart grids?

    Author : Sylvie Evelyne Koziel; Patrik Hilber; Per Westerlund; Ebrahim Shayesteh; Iordanis Koutsopoulos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; data analytics; data management; distribution system operators; electrical power grid; machine learning; real-world datasets; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Physical asset management in the electric power sector encompasses the scheduling of the maintenance and replacement of grid components, as well as decisions about investments in new components. Data plays a crucial role in these decisions. READ MORE

  5. 3. On possibilities of smart meters switching at low voltage level for emergency grid management

    Author : Yasir Arafat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution grid; Smart grid; Remote switching; Smart meter.; Power quality; Power quality measurement;

    Abstract : Smart Meter (SM) is an advanced remotely readable energy meter with two-way communication capability which measures the electrical energy in real-time or near-real-time and securely sends data to Distribution System Operator (DSO). A smart metering system is an application of SMs on a larger scale, i.e. READ MORE

  6. 4. 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

  7. 5. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

    Author : Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []
