In order to stabilize the system voltage in a network section (1) that is connected via a device with a variable voltage transformation ratio to a higher-level network (3) and that comprises at least one energy consumption and/or generation unit (8, 10, 11), the voltage transformation ratio is varied in order to vary a system voltage level in the network section (1). At least in one mode of the method, the system voltage level is increased in order to counteract an increase in the system voltage at the energy consumption and/or generation unit (8, 10, 11), and/or the system voltage level is lowered in order to counteract a decrease in the system voltage at the energy consumption and/or generation unit (8, 10, 11). This is effectively possible because the power consumption and/or output of each energy consumption and/or generation unit (8, 10, 11) in the network section is controlled via a characteristic curve of the system voltage present there, the characteristic curve raising the power consumption of the energy consumption and/or generation unit (8, 10, 11) with an increasing system voltage and lowering the power output of the energy consumption and/or generation unit (8, 10, 11) with increasing system voltage. |
