摘　　要：海洋可再生能源有望成为日益频繁的海洋活动的重要能量来源,尤其是对于有长期、持续、原位、无人需求的应用场景,一定程度上可弥补传统缆系岸电和自持电池/燃料供电方式的不足。但海洋可再生能源存在显著的间歇、波动缺陷,储能是克服该缺陷的最有效方式之一。提出了一种应用于海洋可再生能源的存储与释放的水下大型气液混合储能系统概念,融合高压气体在能量密度和水液压在功率密度上的优势。利用AMESim建立了系统仿真模型,分析了系统储能与释能过程中压力、温度等关键参数的变化,研究了系统的运行效率、能量密度及能量传递与转换特性。结果表明,水下气液混合储能系统运行效率可达约58%,但储能能量密度还有待于进一步提升。Marine renewable energy is expected to be an important energy source for increasingly frequent marine activities,especially for long-term,continuous,in-situ and unmanned application scenarios,which can make up for the shortcomings of traditional cable shore power supply and self-contained battery/fuel power supply to a certain extent.However,marine renewable energy has obvious intermitent and fluctuating defects,and energy storage is one of the most effective ways to overcome these defects.In this study,a concept of large underwater hydropneumatic energy storage system applied to the storage and release of marine renewable energy is proposed,which integrates the advantages of high-pressure gas in energy density and hydraulic pressure in power density.The system simulation model is established in AMESim.The changes of system key parameters such as pressure and temperature in charging and discharging processes are analyzed.The operation efficiency and energy density of the system are studied.The results show that the operation efficiency of the underwater hydro-pneumatic energy storage system can reach about 58%,but the energy density needs to be further improved.
