摘要 |
The invention relates to power networks, and in particular to a battery energy source arrangement 4 and voltage source converter system in such network. The battery energy source arrangement comprises a battery energy storage 2, which in turn comprises one or more parallel-connected battery strings 51,..., 5i,..., 5n, and connection means for connecting a voltage of battery strings 51,..., 5i,..., 5n to a load 1. The battery energy arrangement 4 comprises further battery string voltage adapter devices 71,..., 7i,..., 7n connected in series with a respective one of the one or more battery strings 51,..., 5i,..., 5n wherein the battery string voltage adapter devices 71,..., 7i,..., 7n are designed to handle only a fraction of the voltage handled by the battery strings 51,..., 5i,..., 5n. |
