In this work, the supervisory control and monitoring system of a hybrid energy production station is discussed. A functional architecture consisting of a continuous process system, a discrete data acquisition platform, and an automation infrastructure are integrated to introduce and describe supervisory concepts for the efficient online monitoring of such systems. To this end, a motivating system that consists of three main subsystems, an LPG reformer, a High Temperature Polymer Electrolyte Membrane (HT-PEM) fuel cell and a Lithium-Ion battery stack is used that was designed and constructed by CERTH/CPERI. The system explores the integration of the LPG reformer with the HT-PEM fuel cell and their ability to charge the battery stack upon demand. Overall the supervisory system enables the efficient operation of the involved subsystems and controls the power production which is used both to charge the battery stack and serve the local auxiliary subsystems.
