1. 1. On Modelling Ancillary Services Markets: A Time Series Approach

   University essay from KTH/Matematik (Avd.)

   Author : Erik Murray; [2022]
   Keywords : ARIMA; SARIMA; GARCH; load balancing; ancillary services; electrical grids; FCR-D; ARIMA; SARIMA; GARCH; lastbalans; stödtjänster; kraftnät; FCR-D 2;

   Abstract : So-called ancillary services (AS) have always been critically important for the functioning of an electrical grid, and are becoming even more so with the advent of renewable energy sources. Ancillary services are traded on open markets, and trading on these markets is arguably even more difficult to model than on traditional markets. READ MORE

3. 2. What would be the highestelectrical loads with -20°C inStockholm in 2022 ? : A study of the sensitivity of electrical loads to outdoor temperature in Stockholm region.

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Magali Mellon; [2022]
   Keywords : Data-driven approach; Electrical load forecasting; Temperature sensitivity; Linear Regression; Time series analysis; SARIMAX;

   Abstract :  In the last 10 years, no significant increase in the peak electricity consumption of the region of Stockholm has been observed, despite new customers being connected to the grid. But, as urbanization continues and with electrification being a decisive step of decarbonization pathways, more growth is expected in the future. READ MORE

4. 3. Short-term Forecasting of EV Charging Stations Power Consumption at Distribution Scale

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Milan Clerc; [2022]
   Keywords : Electric Vehicles; Electrical grid; Ancillary services; Time series; Gradient Boosted Trees; Recurrent Neural Networks; ARIMA.; Elbilar; Elnät; Tidsserie; Återkommande neurala nätverk; Maskininlärning.;

   Abstract : Due to the intermittent nature of renewable energy production, maintaining the stability of the power supply system is becoming a significant challenge of the energy transition. Besides, the penetration of Electric Vehicles (EVs) and the development of a large network of charging stations will inevitably increase the pressure on the electrical grid. READ MORE

5. 4. An evaluation of flexibility in the EU-project CoordiNet : Could flexibility markets be a solution to capacity shortage?

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Taru Luttinen; Linnéa Eronen; Emma Wiss; [2020]
   Keywords : Coordinet; capacity shortage; flexibility; Uppsala; load forecasts; electricity grid;

   Abstract : This bachelor thesis examines the part of the EU-project CoordiNet based on Vattenfall Distribution AB and their commitment in the project. The aim and purpose of CoordiNet are to find possible solutions on capacity shortage through coordination between customer -DSO -TSO achieving a more efficient usage of the electrical grid.

6. 5. Techno-economic analysis of Battery Energy Storage Systems and Demand Side Management for peak load shaving in Swedish industries

   University essay from KTH/Kraft- och värmeteknologi

   Author : Benjamin Skog Nestorovic; Douglas Lindén; [2020]
   Keywords : Peak load shaving; battery energy storage system; demand side management; Fast Frequency Reserve market; power tariff; Effektoppsreducering; batterilagringssystem; efterfrågeflexibilitet; Fast Frequency Reserve; effekttariffer;

   Abstract : The Swedish electrical grid has historically been robust and reliable, but with increased electrification in numerous sectors, out-phasing of nuclear power and a high market diffusion of wind power, the system is now facing challenges. The rotational energy in the system is expected to decrease as a result of higher shares of intermittent energy sources, which can affect the stability of the grid frequency negatively. READ MORE
