Description

This paper investigates the feasibility and operational considerations of green hydrogen production in islanded hybrid photovoltaic (PV) plants. These plants operate exclusively during daylight hours, using solar energy as the main source. To mitigate power fluctuations in PV generation, a battery energy storage system (BESS) is integrated to supplement the plant's power during periods of low solar irradiation. Key considerations include the operation of power converters via communication links, specifically addressing the challenges associated with communication delays. These delays will be managed to minimise their impact on system stability. In this study, voltage commands will be sent remotely and used to calculate power references locally to feed the loads. Additionally, the challenges that arise when working with commercial converters that only allow the reception of active and reactive power commands are highlighted. Strategies are discussed to maintain system stability and optimise the performance of the hybrid plant, ensuring efficient and reliable operation. This work contributes to the technical knowledge necessary for the development green hydrogen production through distributed generation plants.
