1. 11. Development of a Plug and Play Solution for Commercial Off-grid Solar Refrigeration : Presenting a Battery Supported System Providing the AC Power Required to run a Coolfinity 300L Commercial Refrigerator

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

   Author : Martijn de Groot; [2021]
   Keywords : Solar refrigeration; Off grid refrigeration; Photovoltaic performance estimation; DC to AC conversion;

   Abstract : In this report the design and testing of a plug and play system to run Coolfinity’s Icevolt 300 refrigerator on solar panels is discussed. Such a system will be able to provide adequate cooling for food & beverages in area’s with unreliable or no electricity available. READ MORE

3. 12. Local energy system - Comparing direct current (LVDC) and alternating current (LVAC)

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Markus Alm; [2020]
   Keywords : Local energy system; LVDC; Technology and Engineering;

   Abstract : This thesis uses a case study to compare the viability of using direct current instead of alternating current to supply power to 5 buildings in a local energy system (LES). The case study sought to show how using LVDC instead of LVAC could increase the effectiveness of solar panels (PV), batteries and interconnecting buildings into a local energy system (LES).

4. 13. Load following in a Swedish nuclear power plant

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Jacob Bjurenfalk; [2020]
   Keywords : chemical engineering; nuclear power; load following; process engineering; electricity production; APROS; Simulations; swedish power gird; kemiteknik; Technology and Engineering;

   Abstract : The energy system in Sweden is currently under a great transformation, where the part of weather dependent energy sources, so called intermittent sources, like solar and wind power will get greater share in the total production of electricity while the production from stable energy sources like nuclear power is decreasing. For a long time, the nuclear power have been operating at baseload and the hydropower as flexible, though, due to the change in the current power system, nuclear power plants may need to transit to flexible operation and apply load following.

5. 14. Techno-economic analysis of retrofitting existing fuel stations with DC fast chargers along with solar PV and energy storage with load flow analysis

   University essay from KTH/Energiteknik

   Author : Nilanshu Ghosh; [2020]
   Keywords : Electric vehicle charging; DC fast chargers; Load flow analysis; EV charging stations; CIGRE LV networks; Elfordonsladdning; DC-laddare; Lastflödesanalys; EV-laddstationer; CIGRE LV-nätverk;

   Abstract : The increasing number of electric vehicles (EVs) in the transport sector has rendered the conventional fuel-based vehicles obsolete along with the fuel filling stations. With the growth in EVs, there has been an increase in the public charging infrastructure with fast charging equipment being used to charge the EVs in least possible time and also address the issue of ‘range anxiety’ among the EV owners.

6. 15. An Estimation Method for PV Hosting Capacity of Distribution Grids

   University essay from

   Author : Kassem Ezzeddine; [2020]
   Keywords : PV; hosting capacity; overvoltage; transformer overload; voltage drop; voltage rise; penetration level; common path;

   Abstract : The Swedish Energy Agency has a target to increase solar photovoltaics (PV) power production by up to 5-10% of the total electricity demand by the year 2040. The PV potential for the residential market is high and its contribution to the total installed PV capacity is expected to increase significantly. READ MORE
