    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Lejla Alibegovic; Emelie Freiland Paulsson; [2021]
    Keywords : Harmonics; microgrid; local energy system; NEPLAN; Technology and Engineering;

    Abstract : “Affordable and clean energy” is EUs 7th Sustainable Development Goal and includes an increase of renewable energy generation in the global energy mix. A lot of the responsibility falls on the energy sector to transform and obtain solutions for a more sustainable future. READ MORE

  3. 12. Optimal Control Actions in an Electrical Grid with Variable Renewable Energy Sources: Evaluation of the ANM4L Control Algorithms

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Erik Boman; [2021]
    Keywords : Technology and Engineering;

    Abstract : The increasing amount of renewable energy in the electrical grid comes with several challenges, of which overvoltage and congestion (overcurrents) are the subjects of this work. One flexible way of handling these problems is active management by some control system. READ MORE

  4. 13. Passive estimation of supply impedances at the meterpoint

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zhanzhan Liu; [2021]
    Keywords : Impedance estimation; Loop theory; System fault detection; Impedansuppskattning; Loopteorin; Systemfelupptäckt;

    Abstract : Modern digital energy meters are installed between the distribution network and customers. Network operators and customers can use those meters to monitor electrical parameters, i.e., voltages and currents and to calculate statistics such as RMS value, fundamental Fourier component, etc. READ MORE

  5. 14. Analysis of Market-Based Flexibility Services- An Evaluation of Flexible Resources’ Indirect Impact on Network Congestion.

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Tobias Gunneberg; [2021]
    Keywords : Local flexibility markets; Demand-side flexibility; Congestion management; Load shifting; flexible resources; Technology and Engineering;

    Abstract : Capacity shortages in electricity grids can impose significant costs on society due to missed investments in industry. Due to limited profit opportunities and long lead times, grid reinforcements are not a viable solution to the problem, which must therefore be prevented through efficient use of existing grid resources.

  6. 15. Implementation of an Arc Model for MV Network with Resonance Earthing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Muhannad Almulla; [2020]
    Keywords : Distribution system; electrical arc; high impedance fault; Petersen coil; resonance earth.;

    Abstract : The most common fault type in electric power systems is the line to groundfault. In this type of faults, an electrical arc is usually developed. The thesispresents a mathematical model that describes the behavior of the arc during afault. READ MORE
