Energy Management of Hydrogen-Storage Photovoltaic Generation System with a Function of Suppressing Short-Period Components

Abstract

The output power of photovoltaic generation (PV) systems changes with the variation in the solar irradiance and temperature of the PV panel surface. The change in output power influences the power quality of the power system. Therefore, a PV system with an electrolyzer (ELY) is proposed to prevent the degradation of the power quality. The proposed system converts the fluctuating components in the PV power fluctuations into hydrogen, which is supplied to fuel cell vehicles. To realize a stable hydrogen supply chain, it is necessary to manage the hydrogen produced by the ELY. This paper proposes a novel method for energy management of a hydrogen-storage PV system with a function of suppressing the short-period components in the PV power. It is verified that the proposed energy management method is effective for reducing the fluctuations of the PV power and the establishment of a hydrogen supply chain.
