  1. 1. Implementation of battery energy storage systems in the Swedish electrical infrastructure

    University essay from KTH/Kemiteknik

    Author : Gustav Arnberg; [2022]
    Keywords : Battery energy storage systems; BESS; Li-ion batteries; Frequency regulation; Business case; Implementation of battery energy storage systems; Swedish electrical infrastructure; BESS; Li-jon batterier; Frekvensreglering; Affärsfall; Implementering av batterilagringssystem; Svensk elinfrastruktur;

    Abstract : Detta examensarbete utreder den tekniska och ekonomiska passbarheten av batterilagringssystem (BESS) inom den svenska el infrastrukturen. Syftet är att konstruera tre olika affärsfall för att representera den tekniska och den ekonomiska passbarheten av BESS inom den svenska el infrastrukturen, specifikt med uppkoppling mot distributionsnätverket på den regionala nivån, 6 kilovolt till 132 kilovolt (kV).

  2. 2. Frequency regulation in the Nordic synchronous system : The possibility for solar parks to provide ancillary services

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Keywords : ;

    Abstract : The Paris Agreement stipulates that the participating countries and areas agree to work toward limiting the global average temperature increase “to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels” (The United Nations, 2015).

  3. 3. Smart charging of an electric bus fleet

    University essay from Uppsala universitet/Elektricitetslära

    Author : Emil Färm; [2021]
    Keywords : Smart charging; Electric vehicle; EV; Electric buses; Bus depot; Electrification; Frequency regulation; FCR; Load balancing; Electrical power systems; Smart laddning; Elfordon; EV; Elbussar; Bussdepå; Elektrifiering; Frekvensreglering; FCR; Lastbalansering; Elektriska system; Elnät;

    Abstract : Controlling the balance of production and consumption of electricity will become increasingly challenging as the transport sector gradually converts to electric vehicles along with a growing share of wind power in the Swedish electric power system. This puts greater demand on resources that maintain the balance to ensure stable grid operation. READ MORE

  4. 4. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

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

    Author : Kristinn Arnar Ormsson; [2021]
    Keywords : Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

    Abstract : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.

  5. 5. Competitiveness in Power System Frequency Regulation Markets : Competitive analysis of the FCR-D up regulation market in Sweden

    University essay from KTH/Energiteknik

    Author : Yu-Hsuan Li; [2021]
    Keywords : ;

    Abstract : The growing share of weather-dependent power generation in the Swedish power system is challenging the stability of the whole system. Therefore, the need to increase system flexibility by frequency regulation reserves is enlarged. Nowadays, the reserves are mainly supplied by Hydropower. READ MORE
