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

    University essay from Linköpings universitet/Fordonssystem; 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
