Evaluation of Design Issues and Automation Infrastructure in a Solar-Hydrogen Production Unit at CERTH in Thessaloniki

Abstract

Objective of the presented study is to evaluate the technical and design issues required prior to the full operation of a solar-hydrogen integrated system. The required measurements, sensors and control elements are a prerequisite for a flexible automation structure and finalization of the process flowsheet. The control strategy and system monitoring are realized on an industrial Supervisory Control and Data Acquisition (SCADA) system. The control strategy is further independently developed based on the system mathematical model and according to the theory of Hierarchical Control. Its evaluation is performed through an one-year simulation study for the conditions of region of installation where the effect of the main system variable on the overall operation is reported.
