  1. 11. Allowing more solar power connected to the grid, using thermal and ageing models of distribution transformers.

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Amena Khatun; [2021]
    Keywords : electric power distribution; solar power; renewable-electricity production; hosting capacity; distribution transformers; dynamic thermal rating; component ageing; component overloading.;

    Abstract : Increasing amounts of solar power connected to the low-voltage network will adversely affect the performance of the network. The two impacts that will most often set the limit are overvoltage with the customers and overloading the distribution transformer. READ MORE

  3. 12. Energy Storage for Voltage Control in LV Grids

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Ida Samnegård; [2021]
    Keywords : Technology and Engineering;

    Abstract : This thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. READ MORE

  4. 13. 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).

  5. 14. Battery Sizing and Placement in the Low Voltage Grid including Photovoltaics

    University essay from Linköpings universitet/Fordonssystem

    Author : Alexander Klasson; Philip Melin; [2020]
    Keywords : ;

    Abstract : Installations of photovoltaic power production increases each year. This can have a negative consequence on the distribution grid where the voltage can increase. The electric distribution companies in Sweden have a responsibility in keeping the grid at certain voltages, and have to reinforce the grid if these voltages are outside these levels. READ MORE

  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
