Stable power supply of an independent power source for a remote island using a Hybrid Energy Storage System composed of electric and hydrogen energy storage systems

We propose a self-sustaining power supply system consisting of a Hybrid Energy Storage System (HESS) and renewable energy sources to ensure a stable supply of high-quality power in remote islands. The configuration of the self-sustaining power supply system that can utilize renewable energy sources effectively on remote islands where the installation area is limited is investigated. It is found that it is important to select renewable energy sources whose output power curve is close to the load curve to improve the efficiency of the system. The operation methods that can increase the cost-effectiveness of the self-sustaining power supply system are also investigated. It is clarified that it is important for increasing the cost effectiveness of the self-sustaining power supply system to operate the HESS with a smaller capacity of its components by setting upper limits on the output power of the renewable energy sources and cutting the infrequent generated power.(c) 2022 Hydrogen Energy Publications LLC.

Automated summary

In this study, a self-sustaining power supply system composed of a Hybrid Energy Storage System (HESS) and renewable energy sources is proposed for remote islands. The research examines the configuration of the system to effectively utilize renewable energy sources in areas with limited installation space. It is found that selecting renewable energy sources with output power curves that closely match the load curve is crucial for improving system efficiency. The study also investigates operational methods that can enhance the cost-effectiveness of the self-sustaining power supply system, emphasizing the importance of setting upper limits on the output power of renewable energy sources and reducing infrequent generated power.
