Abstract

The invention relates to power networks, and in particular to a battery energy source arrangement and voltage source converter system in such network. The battery energy source arrangement includes battery energy storage, having one or more parallel-connected battery strings and a mechanism for connecting a voltage of the battery strings to a load. The battery energy source arrangement further includes battery string voltage adapter devices connected in series with respective ones of the one or more battery strings wherein the battery string voltage adapter devices are designed to handle only a fraction of the voltage handled by the battery strings.
