    Keywords : Wind power; offshore wind farm; reactive power; reactive power market; grid code; RfG; voltage stability; Vindkraftspark; havsbaserad vindkraft; reaktiv effekt; reaktiv effektmarknad; nätkod; spänningsstabilitet;

    Abstract : Year 2040 the goal is to have a 100 % renewable Swedish energy system. Svenska kraftnät (Svk) predicts fully decommissioned nuclear power plants and an increased amount of connected wind power plants, especially offshore, year 2045. READ MORE

  3. 2. Grid Scale Storage Placement In Power Systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Andreas Bodegård; [2022]
    Keywords : FFR; frequency regulation; PowerFactory; DIgSILENT; grid scale storage; inertia; power system; rotor-angle stability; frequency stability; modal analysis; kundur two area model; nordic32;

    Abstract : The increasing amount of renewable energy sources is applying more and more pressure on today’s power system. Additionally, plannable sources of energy, which are mostly non-renewable, are being decommissioned at a high rate to combat climate change. READ MORE

  4. 3. Assessing the Impact of High Grid Penetration of Renewable Energy on Power System Stability

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

    Author : William Nordberg; Alexander Leijonhielm; [2022]
    Keywords : Power System Stability; Variable Renewable Energy; Power System Stabilizers; Grid Following Converters; Grid Forming Converters;

    Abstract : In this report, the effect that a higher penetration ofrenewable energy sources has on electric power grid stability isevaluated. The report also compares different methods of stabilizingan unstable grid. READ MORE

  5. 4. 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.

  6. 5. Sustainable Implementation of Photovoltaic Technologies in Mauritius : A study on the energy system in Mauritius and the effect of solar power generation on frequency stability

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Maria Isabel Bang Jensen; Simon Lundberg; [2020]
    Keywords : Isolated energy system; photovoltaic technologies; frequency stability; system inertia; grid readiness; renewable energy; sustainable energy mix; Mauritius; PV shutdown; N-1 security; Isolerad energisystem; solceller; frekvensstabilitet; svängmassa; förnybar energi; hållbar energimix; Mauritius; produktionsbortfall; N-1 säkerhet;

    Abstract : Mauritius is an isolated island with ambitious targets for renewable energy generation and plans to invest in more solar power. The aim of this study is to assess how the implementation of photovoltaic technologies might affect the frequency stability in Mauritius and thus assess whether solar power can help the country obtain their targets for green energy generation.
