   Abstract : On February 6, 2023, two earthquakes (7.8MW and 7.7MW) struck Turkey within nine hours, resulting in over 50,000 fatalities and significant damage to critical infrastructures (CI) which provide services essential for the functioning of society. READ MORE

3. 2. Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition

   University essay from

   Author : Ellen Blanksvärd; Frida Svensson; [2023-09-21T12:07:03Z 2023-09-21T12:07:03Z 2023 2023]
   Keywords : battery storage; variation management; flexibility services; peak shaving; load shifting; demand side management; rental business; electrification; construction equipment; construction sites;

   Abstract : Construction sites are facing challenges with high power peaks due to electrificationof heavy equipment where potential consequences are increased power tariffs locallyand risk of limited power supply. Another development is an increased intermittentpower supply due to more wind- and solar power in the electricity system, whichcauses price fluctuations. READ MORE

4. 3. Forecasting Volatility of Electricity Intraday Log Returns with Generalized Autoregressive Score Models

   University essay from Göteborgs universitet/Graduate School

   Author : Gustav Veres; Philip Ahlfridh; [2023-06-29]
   Keywords : ;

   Abstract : We forecast volatility of electricity intraday log returns with Generalized Autoregressive Score (GAS) models. We extend our GAS models with variables representing the difference between the public’s expectation of weather and energy load and the actual outcome using a restricted ARMA(4,4) model. READ MORE

5. 4. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

   Author : Doris Dijak; Elin Torstensson; [2023]
   Keywords : Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

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

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

   Author : Theodor Ingman; Henrik von Sivers; [2023]
   Keywords : ;

   Abstract : 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. READ MORE
