The aim of this study is to analyze the behavior and the performance of an integrated power plant in which a renewable energy system, based on photovoltaic and wind power units, is coupled with a hydrogen energy storage system. The storage system is based on the ReSOC (Reversible Solid Oxide Cell) technology, that is an electrochemical device able to work both as fuel cell and as electrolyzer. The role of the storage unit is to permit a constant power grid feeding. Thus, the integrated power system has to be managed in order to feed into the grid the electric energy that the renewable power plant is able to produce during its annual operation, but with a power supplying that is constant in time. This operation mode implies that if the stored hydrogen is not available to assure a constant power feeding, an auxiliary power system is used for satisfying the power requirement.
