摘要

power plant with capacity to charge electric batteries, charging station and use of the power plant. The present invention relates to a power plant with a capacity for charging electric batteries which is a power transmission power plant comprising a voltage source converter (1), an alternating voltage network (14) connecting a dc side. alternating voltage of the converter and a direct voltage part (7) connected to the direct voltage side of the converter. The converter (1) has a serial connection of switching cells (8) each having at least one capacitor for storing power. electric batteries may be connected in parallel with said capacitor, and their charging state may be influenced by controlling the voltage source converter switching cells via a control arrangement (15).
