  1. 1. Top-down cost assessment and market regulatory conditions affecting BESS feasibility in the Spanish framework : Exploring the viability of utility-scale stand-alone Battery Energy Storage Systems in Spain

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pere Abelló Sunyer; [2023]
    Nyckelord :Battery Energy Storage Systems BESS ; Regulatory framework; Operational optimization; Economic viability;

    Sammanfattning : This thesis report provides a comprehensive analysis of the regulatory landscape governing Battery Energy Storage Systems (BESS) in Spain and offers insights into their operational optimization and economic viability. The study centers on a 40 MW BESS and explores three distinct case studies, each representing varying system durations (one, two, and four hours) and two different electricity price scenarios (2019 and 2022).

  3. 2. Design och framtagning avprototyp för reglering avhandtagsvärme på bensindriven motorsåg

    M1-uppsats, Karlstads universitet

    Författare :Axel Wedin; [2023]
    Nyckelord :;

    Sammanfattning : Husqvarna Group is a company specializing in forest and garden products. Among these products are chainsaws that incorporate functionality for handle heating. The current handle heating system is unregulated, and this report therefore addresses the development and construction of a prototype for controlling handle heating. LÄS MER

  4. 3. Energilager i kyrkan och dess systemnyttor : Batterier i kyrkan och hur de kan bidra till ett stabilare elnät

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Axel Eriksson; David Norman; [2023]
    Nyckelord :stödtjänster; batterisystem; energilager; peakshawing; spänningsreglering; flexibilitetsmarknader; kyrkan;

    Sammanfattning : Many of the over 3300 churches in Sweden are only used a couple of times a week and are kept cold in between sessions. The occasional heating results in a power spike which burdens both grid and wallet in form of an increased grid fee. With the help of a battery and peak shaving, the peak can be lessened. LÄS MER

  5. 4. Assessing the Benefits of Fossil-Free Gas Turbines in Distribution Networks : A Case Study in Västerås

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Fredrik Hansell; Axel Vällfors; [2023]
    Nyckelord :Gas turbine; power system stability; balancing markets; hydrogen; eMethanol; Gasturbin; kraftsystemstabilitet; balansmarknader; vätgas; e-metanol;

    Sammanfattning : As the share of weather-dependent renewable electricity production increases, the demand for power system flexibility grows. In the Swedish power system, gas turbines have historically been utilised for back-up power generation. LÄS MER

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

    Master-uppsats, KTH/Kemiteknik

    Författare :Gustav Arnberg; [2022]
    Nyckelord :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;

    Sammanfattning : 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).
