Towards a domain-specific refinement of Process Orchestration Layers for Modular Electrolysis Plants

At present, Process Orchestration Layers lack necessary functionalities to control individual modules in modular electrolysis plants based on electricity supply and hydrogen demand. This paper addresses the domain-specific refinement of Process Orchestration Layers to operate a modular electrolysis plant in an economical manner. The refinement, consisting of the Demand Side Management and PEA-Scheduling, allows the integration of forecasts from electricity sources and hydrogen sinks to determine the operating points of individual electrolysis modules. First, the requirements for such a refinement concept are established and then the developed concept is illustrated by the use case of a hydrogen refueling station.
