This paper presents the modeling and energy management system (EMS) of a hybrid marine‐hydrogen power generation system. The proposed system aims to convert the static nature of the tidal energy into an active system by using a hydrogen energy storage system. The system of the tidal energy converter (TEC) considers the fixed pitch direct drive technology while the hydrogen system consists of 1.0 MW (megawatt) proton exchange membrane electrolyzer. A MATLAB/Simulink based model has been developed for studying and evaluating the effectiveness of the proposed EMS. The developed model depends on scaling up a 50 W proton exchange membrane (PEM) electrolyzer model to 1 MW scale by adapting the model parameters for providing the same key performance indicators (KPIs). The EMS aims to convert all the TEC generated energy into hydrogen with considering the efficient and safe operation of the different system components. Thus, the loss minimization (efficiency maximization) of the tidal turbine generator is integrated as one of the EMS goals to evaluate its effect on hydrogen production. The generator of the TEC is controlled by two different strategies for estimating the surplus hydrogen that could be produced. The strategies are the maximum torque/ampere and the loss minimization.

混合潮汐涡轮-氢微电网的能源管理：损失最小化策略

本文介绍了混合海洋氢发电系统的建模和能源管理系统 (EMS)。所提出的系统旨在通过使用氢能存储系统将潮汐能的静态性质转换为主动系统。潮汐能转换器（TEC）系统采用定距直驱技术，氢气系统采用1.0 MW（兆瓦）质子交换膜电解槽。已经开发了基于 MATLAB/Simulink 的模型来研究和评估所提议的 EMS 的有效性。开发的模型取决于通过调整模型参数以提供相同的关键性能指标 (KPI)，将 50 W 质子交换膜 (PEM) 电解槽模型放大到 1 MW 规模。EMS 旨在将所有 TEC 产生的能量转换为氢气，同时考虑到不同系统组件的高效和安全运行。因此，潮汐涡轮发电机的损失最小化（效率最大化）被整合为 EMS 目标之一，以评估其对制氢的影响。TEC 的发生器由两种不同的策略控制，用于估算可能产生的过剩氢气。策略是最大扭矩/安培和损耗最小化。TEC 的发生器由两种不同的策略控制，用于估算可能产生的过剩氢气。策略是最大扭矩/安培和损耗最小化。TEC 的发生器由两种不同的策略控制，用于估算可能产生的过剩氢气。策略是最大扭矩/安培和损耗最小化。
