  1. 6. Analysis of synthetic inertia using wind turbines for frequency stability in power systems

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Carl Herrlin; [2022]
    Keywords : Synthetic inertia; wind turbines; energy systems; electrical power; Technology and Engineering;

    Abstract : With the large expansion of renewable energy sources such as wind- and solar, the stability and quality of electrical power can be affected. The transition towards large-scale wind power offers many opportunities to maintain stability by using power converters to create synthetic inertia. READ MORE

  3. 7. Improvements of an Embedded System for Measuring Supended Particles

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Johan Olsson; Joseph Strandnes; [2022]
    Keywords : transmittance; concentration; suspended particle; microcontroller; microprocessor; LED; photodiode; water treatment; optical;

    Abstract : Particle suspension is a phenomenon when solid particles get trapped in a liquid. This phenomenon is a common occurrence in the water treatment industry. It is typically measured continuously throughout the treatment process to ultimately ensure high water-quality. READ MORE

  4. 8. Condition Based Reliability Evaluation and Maintenance Strategy for Battery Energy Storage System

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

    Author : Novalie Hou; [2022]
    Keywords : Battery Energy Storage System; Reliability Evaluation; Maintenance Strategy; Batterienergilagringssystem; Tillförlitlighets Evaluering; Underhållsstrategi;

    Abstract : The electrical grid balances production capacity and demand in real-time. With an increased demand for renewable energy sources, challenges such as stability of the grid, the balance between generation and demand, and power quality occur. READ MORE

  5. 9. Future Nordic Grid Frequency Quality : A quantitative simulation study of current and potential frequency control methods with emphasis on synthetic inertia

    University essay from Uppsala universitet/Elektricitetslära

    Author : Emil Arvidsson; [2021]
    Keywords : grid frequency; synthetic inertia; frequency control; power grid; hydro power;

    Abstract : The power grid faces stability problems due to loss of inertia. The ancillary services balancing the system must be improved to maintain stability. READ MORE

  6. 10. The role of location of low inertia in power systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bashar Alahmad; [2021]
    Keywords : Low inertia; Frequency stability; Rotor-angle stability; Nordic 32; Kundur; PowerFactory; Small-signal stability; Inter-area oscillation; Rate of Change of Frequency.;

    Abstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.
