  • Method for operating a low-voltage electrical system
    Patent number: 8212397
    Abstract: Decentralized power generation installations are connected to a low-voltage electrical system LV. These installations can make available control energy. The control of the active power output by the power generation installations into the low-voltage electrical system takes place by means of active variation of the system voltage by means of a transformer T with a variable transformation ratio.
