1. 1. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

   Master-uppsats, KTH/Energiteknik

   Författare :Timon Renzelmann; [2024]
   Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

   Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Sophia Larbi Engelbrektsson; [2023]
   Nyckelord :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;

   Sammanfattning : 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.

4. 3. How closely does electricity production follow price signals?

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

   Författare :Théo Sa Cunha; [2021]
   Nyckelord :Power system; the Nordics; day-ahead prices; production; balancing contribution; relative market value; correlation coefficient; spectral analysis; time horizons; flexibility; variation management; Elsystem; Norden; day-ahead-priser; produktion; balansbidrag reglerbidrag; relativa marknadsvärden; korrelationskoefficient; spektralanalys; tidshorisont; flexibilitet; balanshållning;

   Sammanfattning : This thesis investigates the relation between the day-ahead electricity market prices and the electricity production in the Nordic synchronous area of the European electric power system by looking into the market data ranging from 2015 to the current time. The increasing penetration of variable renewable energy sources, coupled with the deeper electrification in various sectors of the economy, has led to a higher volatility in the market, e. LÄS MER

5. 4. Customer Experience without Customer Contact: DSOs Adapting to a Supplier Centric Market : A multiple case study of Swedish DSOs

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

   Författare :Erik Bexelius; John Diklev; [2020]
   Nyckelord :;

   Sammanfattning : Structural changes are looming in the Swedish electricity system. Underlying forces pushing for industry practices to transform are sustainability goals, digitalisation and free market ambitions. LÄS MER

7. 5. Optimal Day-Ahead Scheduling and Bidding Strategy of Risk-Averse Electric Vehicle Aggregator : A Case Study of the Nordic Energy and Frequency Containment Reserve Markets

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jacob Dalton; [2018]
   Nyckelord :;

   Sammanfattning : The Nordic synchronous grid is facing a number of challenges. The ongoingphaseout of synchronous generation coupled with increased penetration ofintermittent renewable generation is leading to reduced system inertia. LÄS MER
