Abstract

Due to the inherent characteristics of wave resources, wave energy generation (WEG) exhibits impulsive characteristics that needs to be smoothed out before being utilized. The degradation loss of a single battery system to consume the impulsive power is significant. Considering the high energy density and storage portability of hydrogen, a hybrid system combining battery and flexible water electrolysis system is a promising choice for wave energy consumption. However, more diverse and complex consumption devices will introduce more operational conflicts and coordination challenges. Therefore, the paper firstly explores the dynamic characteristics of WEG, taking into account the comprehensive external environment and internal control factors. Then, the contradictory boundaries and collaborated domains between the characteristics of impulsive WEG and the consumption devices are clarified through theoretical analysis. Subsequently, a movable electric-hydrogen supplier (MEHS) powered by wave energy was proposed. Considering the requirements of internal multi-energy flow coupling and external multi-spatiotemporal interaction, a scheduling model is established to schedule energy capture, storage, and supply behavior of MEHS. The simulation results show that the proposed flexible scheduling framework can effectively match the dynamic characteristics of different devices, and maximize the utilization of wave energy resources for island microgrids.
