Description

Prior ArtThe number and size of announced water electrolysis projects for the production of "green" hydrogen last increase sharply. Current solutions for electrolysis systems focus on two concepts: On the one hand, container solutions in which the entire electrolysis system is located in one or a few containers. On the other hand, medium and large electrolysis installations with a power consumption of 1 MW up to several GWs, which are projected from individual components or which are constructed from prefabricated modules.Disclosure of the InventionRequirements for medium and large electrolysis installations are, in addition to a high overall efficiency and a high installation safety with a robust and long operation and short maintenance times, a dynamic operating mode, a simple exchange of defective components and simple integration of new components in order to increase the installation capacity. In this case, cost-intensive components, such as, for example, electrolysis stacks, are to be saved during operation. Satisfying these requirements is difficult with current control concepts for large installations.For example, when all system components of the system are controlled centrally, disturbances in one part of the system may also cause down times for other parts of the system that would actually be operational. Moreover, such a central control requires a complex software architecture.According to aspects of the invention, an electrolysis module cluster and a multi-electrolysis module cluster according to the features of the independent claims are proposed. Advantageous embodiments are the subject matter of the dependent claims and of the following description.According to one aspect of the invention, an electrolysis module cluster having a first electrolysis module and a second electrolysis module is proposed. The respective electrolysis module has an electrolysis stack system with a multiplicity of actuators and a multiplicity of sensors. In addition, the respective electrolysis module has an output connection which is configured to provide generated electrolysis gases, a water supply connection and power electronics which is coupled to the electrolysis stack system for providing electrical energy. The respective electrolysis module furthermore has control and regulating electronics which are each coupled in terms of signal to the multiplicity of actuators and sensors and to the power electronics. The control and regulating electronics are configured to operate the respective electrolysis stack system independently of the regulation based on signals from the respective plurality of sensors of the electrolysis stack system and based on an electrolysis product quantity requirement provided in each case for the electrolysis module and based on an operating mode of a plurality of operating modes provided in each case for the respective electrolysis module, the respective electrolysis stack system, by means of the actuators, and the power electronics. The respective control and regulating electronics of the first electrolysis module and of the second electrolysis module is configured and set up to be coupled signal-wise to a control interface for the provision of the respective operating mode and / or a respective electrolysis production quantity requirement for the regulation-autonomous operation of the respective electrolysis module.The electrolysis stack system may comprise an electrolysis stack, a plurality of actuators and a plurality of sensors. The power electronics can be configured to be coupled to a power supply network, in particular by means of a transformer. The respective electrolysis module can be configured to be operated with a multiplicity of operating modes, which can be selected in particular.By means of the electrolysis module cluster, for example, a medium or large electrolysis systems can be constructed in that a multiplicity of electrolysis modules, which each have hardware- and software-compatible and / or structurally identical interfaces and / or signal interfaces, can be connected to form a cluster of respectively regulation-autonomous electrolysis modules. The cluster can be controlled as a unit by means of a control interface on the basis of the compatible interfaces and / or signal interfaces in order to be able to produce a provided electrolysis production quantity requirement.
