Abstract: Randomness and intermittency of renewable energy generation are inevitable impediments to the stable electricity supply of isolated energy systems in remote rural areas. This paper unveils a novel framework, the electric–hydrogen hybrid energy storage system (EH-HESS), as a promising solution for efficiently meeting the demands of intra-day and seasonal peak shaving. A hierarchical time discretization model is applied to achieve unified operation of hydrogen and electric energy storage to simplify the model. Furthermore, an operation strategy considering the energy interaction between ESSs is introduced, while an optimization model of hydrogen storage working interval within the state transition limit is designed to improve the utilization of hydrogen storage. Numerical tests are conducted to validate the approach, demonstrating that the proposed energy storage structure and operation strategy can effectively improve the utilization of energy storage and ensure the energy supply of the system, which will provide a reference for the sustainable operation of renewable energy systems in the future.
