  1. 1. Evaluation of key performance indices for frequency quality : A method for evaluating frequency stability in the Nordic power system

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

    Author : Sophia Larbi Engelbrektsson; [2023]
    Keywords : Ancillary Services; Kinetic Energy; Frequency Dependent Load; Frequency Stability; Frequency Quality; KPI; Nordic Power System; Frekvensberoende Last; Frekvenskvalité; Frekvensstabilitet; Kinetisk Energi; Nordiska Elsystemet; Nyckeltal; Stödtjänster;

    Abstract : The Nordic power system is in a changing phase, with more power electronic interfaced connections, and HVDC connections to other synchronous areas, which impacts the frequency quality. This is a challenge for the transmission system operator of Sweden, Svenska Kraftnät, who, with the other Nordic transmission system operators, is responsible for the physical balancing of the Nordic power system.

  3. 2. Supporting Frequency Stability With Batteries in Low Inertia Power Systems

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

    Author : Sophie-Linn Karlsson; Tim Asking; [2022]
    Keywords : Battery Power Support; Fast Frequency Reserves; Frequency Containment Reserves; Inertia; Renewable Energy Sources;

    Abstract : As the share of power electronics-based renewable energy sources increases in power systems, the system inertia provided by conventional generation is reduced. Inertia is an important factor in the grid's frequency stability, and with its reduction comes challenges to ensure the reliability of the grid. READ MORE

  4. 3. 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.

  5. 4. Frequency Response from Inverter-Based Generation

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

    Author : Johanna Lindstén; [2020]
    Keywords : ;

    Abstract : The system inertia of the Nordic power system is expected decrease in the future. This is due to an expected reduction in synchronous generation from nuclear and thermal power. This will be compensated by an increase in power from inverter-based generation due to wind power’s expansion in the power system. READ MORE

  6. 5. Decentralized Secondary Frequency Control in an Optimized Diesel PV Hybrid System

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

    Author : Alice Vieira Turnell; [2018]
    Keywords : Solar photovoltaic; frequency stability; decentralized secondary frequency control; reserve allocation; hybrid system; island system; HOMER; PowerFactory; Solceller; frekvensstabilitet; decentraliserad sekundär frekvenskontroll; reservallokering; hybridsystem; ösystem; HOMER; PowerFactory;

    Abstract : This research argues that a diesel-based isolated electrical system can be optimized byintegrating a high share of solar photovoltaic (PV) generation and that the frequencystability of such system can be improved by including the PV participation in frequencyregulation. A case study is developed in order to explore an island’s expansion of theinstalled generating capacity and its optimization. READ MORE
