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.
Cette invention concerne les réseaux dalimentation et en particulier une disposition de source dénergie à batteries 4, ainsi quun système de transformation de tension source dans un réseau de ce type. La disposition de source dénergie à batteries comprend un dispositif de stockage dénergie à batteries 2, qui comprend à son tour un ou plusieurs blocs de batteries montées en parallèle 51,, 5i,, 5n, et des moyens de raccordement pour raccorder une tension fournie par les blocs de batteries 51,, 5i,, 5n à une charge 1. La disposition de source dénergie à batteries 4 comprend en outre des dispositifs dadaptation de tension de bloc de batteries 71,, 7i,, 7n montés en série avec un bloc respectif du ou des blocs de batteries 51,, 5i,, 5n. Lesdits dispositifs dadaptation de tension de bloc de batteries 71,, 7i,, 7n sont conçus pour ne gérer quune partie de la tension gérée par les blocs de batteries 51,, 5i,, 5n.
