Abstract :
The control strategy for a photovoltaic (PV) system with a hydrogen (H2) subsystem consisting of an electrolyzer,
pressurized hydrogen gas storage, and fuel cell has been investigated. Detailed computer simulation models for
TRNSYS have been developed, tested, and verified against a reference system, namely the PHOEBUS plant in J€ulich,
Germany. The basic control strategy and main logical control variables for a PV–H2 system are described. System
performance indicators, parameters, and constraints that can be used to analyze the performance of PV–H2 systems
have been identified. The results from a time series simulation for a typical year are presented. Finally, the importance
of selecting smart control strategies is demonstrated.
