PLANT NETWORK INCLUDING AN ELECTROLYSIS PLANT AND A POWER SUPPLY SOURCE

The invention relates to a plant network (100) comprising an electrolysis plant (1, 1A, 1B), a power supply source (3) with a DC voltage output (7) and a central supply line (5), wherein the central supply line (5) is connected to the DC voltage output (7) of the power supply source (3), so that a direct current can be fed into the central supply line (5) and a central DC network designed for a high voltage is provided to which the electrolysis plant (1, 1A, 1B) is connected via the central supply line (5). The power supply source (3) as a power generator comprises a wind turbine (19) to which a rectifier (13A) with a DC voltage output (7) is connected, wherein the DC voltage output (7) is designed for the high voltage, and wherein a controllable energy storage system (17) is connected to the central supply line (5) which is designed in such a way, that a direct current can be fed into the central supply line (5) by means of the energy storage system (17) as required or can be discharged from the central supply line (5) and fed into the energy storage system (17).In addition, the invention concerns a method for operating a respective plant network (100).
