1. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves
Master-uppsats, Lunds universitet/ProduktionsekonomiSammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER
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)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.

3. Frekvensstyrning med Kaplanturbin
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)Sammanfattning : Det här examensarbetet inriktar sig på att med ett simuleringsprogram försöka utröna om det skulle gå att använda feedback control av löphju-let på en kaplanturbin för att reglera frekvensen ut på elnätet. Detta görs idag med hjälp av att öka eller minska magnetiseringen av generatorn. LÄS MER
4. Energilager i kyrkan och dess systemnyttor : Batterier i kyrkan och hur de kan bidra till ett stabilare elnät
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : 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. The Potential of Data Centre Participation in Ancillary Service Markets in Sweden
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Today’s society already requires a great connectivity network. This need will only increase in the future, and EDGE data centres are concepts meeting this future need, where the computational power is deployed close to the end user. LÄS MER
