摘要

The invention relates to a device for stabilizing electrical networks by a system for influencing the electrical energy consumption of larger consumers, eg. B. for charging electric vehicles, comprising a connection network (N1), a balancing active network (N2) and an adjacent, passive network (N3), wherein higher-frequency measuring means are provided for all occurring voltages and currents. According to the invention, the time-variable energy consumption in the compensating, active network (N2) is modified in such a way that network effects are reduced or network disturbances are compensated by the combination with the determined impedance of connected energy consumers. - Wherein a measuring and analyzing device (1) for measuring and analyzing a time course of voltages and currents of a supply in the connection network (N1) and for characterizing the surrounding networks is provided and - An arithmetic unit (2) is provided for determining a correction signal, and - Wherein a modification device (3) is provided for modifying a control signal for a power controller and - Wherein a power controller (4) is provided which connects a power supply with an energy consumer and - Wherein a bidirectional transmission device (5) is provided for the transmission of target parameters and fault messages, which is connected to a network connection and is connected to the arithmetic unit (2) bidirectional. The invention also relates to an associated method.
