1. 1. Unlocking the Potential of Battery Energy Storage Systems in the Nordic Frequency Regulation Markets : A techno-economic analysis to evaluate long-term profitability

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

   Författare :Theodor Ingman; Henrik von Sivers; [2023]
   Nyckelord :;

   Sammanfattning : As the Swedish power system has increased its shares of production coming from intermittent renewables, the production coming from large rotational units as nuclear, and hydropower, has decreased. Thereby, the power system has become more sensitive to sudden changes between production and consumption of electricity, increasing the risk of disruptions in the electricity grid. LÄS MER

   Sammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER

4. 3. Assessing Offshore Wind System Integration: Comparative Analysis of Floating Photovoltaics, Oscillating Surge Wave Converters, and Battery Energy Storage Systems

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Wilhelm Niilekselä; Douglas Hansson; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. LÄS MER

5. 4. UTILIZING WIND POWER IN GRID BALANCING AT AUTOMATIC FREQUENCY RESTORATION RESERVE AND MANUAL FREQUENCY RESTORATION RESERVE LEVELS

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Yang Lu; [2023]
   Nyckelord :frequency restoration reserve FRR ; balancing markets; wind power integration;

   Sammanfattning : Variable renewables like wind energy are playing an increasingly heavy role in power generation with higher penetration levels. While such trend in electricity spot market is undeniable, how to integrate wind power in the balancing market remains uncertain. LÄS MER

7. 5. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Prashant Niroula; [2023]
   Nyckelord :energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

   Sammanfattning : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. LÄS MER
