Method and device for controlling the stability of a low voltage network

摘要

The method involves feeding electric current to a low-voltage system (1) by a local network transformer (2). The current is conducted in branch current conductors (5a-5c) at which a power consumer and/or a power generator (10) are attached. Current consumption of the consumer, energy input of the generator, current introduction of a main stream conductor in the conductors and/or feeding of the current to the low-voltage system are controlled based on current flow or voltage detected by a sensor so that overload of the conductors is avoided and/or a voltage band is maintained in network areas. The power generator is a photovoltaic system, a wind power plant or a biogas system. The power consumer is a power consuming household or a charging station for electrical cars. An independent claim is also included for a device for controlling stability of a low-voltage network.
