An electrolytic power plant using an electrolysis device which requires one part of the electric energy which is produced by the power plant. The electrolysis device forms a variable load for the constant control network frequency and produces hydrogen and oxygen. The power plant has an oxygen pump, a buffer container, an oxygen distribution line, and an oxygen pump that are used for the accumulated oxygen.

Power plant

The invention relates to a method and a device for supporting the frequency in an electricity network () during a sudden modification of the network load and/or generating power. According to the invention, modifications of the network load and/or generating power, which cause the network frequency to deviate from a predefined value, are compensated by a modification of an additional load (). Said additional load () is preferably configured by a large number of hydrogen-producing electrolysis units (), which can be activated or deactivated for the successive modification of the additional load.
