1. 1. Congestion Management of EV Charging in Distribution Networks

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Adam Rosandell; [2022]
   Keywords : Technology and Engineering;

   Abstract : The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI controllers has been developed.

3. 2. 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.

4. 3. Evaluating the impact on the distribution network due to electric vehicles : A case study done for Hammarby Sjöstad

   University essay from KTH/Energiteknik

   Author : Robert Karlsson; [2020]
   Keywords : Plug-in Electric vehicle PEV ; Peak power; Distribution network; Charging strategies; Energy system modelling; Elbil PEV ; Maximal last; Lågspänningsnät; Laddningsstrategier; Modellering av energisystem;

   Abstract : When the low voltage electric grid is dimensioned electric loads are predicted by analyzing the area by certain factors such as geographical data, customer type, heating method etc. So far, the charging of Plugin Electric Vehicles (PEVs) is not considered as one of these factors.

5. 4. Charge into the Future Grid : Optimizing Batteries to Support the Future Low-Voltage Electrical Grid

   University essay from Linköpings universitet/Fordonssystem

   Author : Mergim Dushku; Julius Kokko Ekholm; [2019]
   Keywords : Optimization; Electric Vehicle; EV; Stationary Battery System; SBS; LV-grid; Electrical Grid; Peak Load; Voltage Variations; fmincon; Future Grid; Vehicle-to-Grid; Vehicle-to-Home; Photovoltaic; PV; Control Theory; Battery; Smart Charging; Nonlinear Programming;

   Abstract : The increase in electric vehicles and photovoltaic power production may introduce problems to the low-voltage distribution grid. With a higher number of electric vehicles, their accumulated charging power might breach the lowest allowed voltage level of the grid. READ MORE

6. 5. Utilizing Privately Owned Flexibilities in the German Distribution System : Technical and Regulatory Framework

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

   Author : Nahal Tamadon; [2019]
   Keywords : ;

   Abstract : This Master’s thesis project aims to define the technical and regulatory framework of asystem flexibility service utilizing distributed flexibilities connected to the low-voltage (LV)level. The flexibility service outlined here is local balancing, with the purpose of increasing theload-generation balance in LV networks using thermostatically controlled loads and ElectricalEnergy Storage (EES) devices.
