Modelling and Validation of a Small Scale Hybrid Photovoltaic-Battery-Electrolyzer System

In this study, the behaviour of a small-scale hybrid energy system is predicted by means of a developed calculation model. In more detail, the experimental setup consists of photovoltaic panels, batteries and an electrolyzer; the mathematical sub-models for each device are provided. These sub-models have been validated by means of experimental data, recorded during laboratory tests. The results show that each sub-model reproduces very well the experimental data and then the whole system model can be applied to identify the optimal management strategy of a solar-to-hydrogen micro-scale system.
