Abstract

Hydrogen fuel cells are gaining popularity as a reliable and efficient sustainable energy source. They have found uses in electric vehicles and microgrid applications. A grid-connected microgrid system with a 60 kW proton exchange membrane fuel cell (PEMFC) is proposed. A PEM fuel cell-based generating unit is studied, using a sliding mode controller (SMC) in the control scheme and a nine-switch converter (NSC) for the system integration. The NSC is used to integrate the FC system with the utility grid and controls the system's power flow. This study is focused on the performance evaluation of the proportional-integral-derivative (PID) and SMC controllers. The controllers' gains are tuned using an improved arithmetic optimization method (IAOA). The article also emphasizes improving system performance and stability by incorporating SMC in the control scheme. The suggested system is exposed to different source and load-side disturbances for performance evaluation. Matlab/Simulink is used to model the proposed system and validated by the real-time OPAL-RT 4510.

使用九个开关转换器的基于 PEMFC 的电网集成系统的 PID 和 SMC 性能分析 - 对比研究

氢燃料电池作为一种可靠、高效的可持续能源，越来越受到人们的青睐。氢燃料电池已在电动汽车和微电网中得到应用。本研究提出了一种带有 60 千瓦质子交换膜燃料电池（PEMFC）的并网微电网系统。研究了基于 PEM 燃料电池的发电机组，在控制方案中使用了滑动模式控制器 (SMC)，在系统集成中使用了九开关转换器 (NSC)。NSC 用于将燃料电池系统与公用电网集成，并控制系统的功率流。本研究的重点是比例-积分-派生（PID）控制器和 SMC 控制器的性能评估。控制器的增益采用改进的算术优化方法（IAOA）进行调整。文章还强调通过在控制方案中加入 SMC 来提高系统性能和稳定性。为进行性能评估，建议的系统暴露于不同的源干扰和负载侧干扰。使用 Matlab/Simulink 对所建议的系统进行建模，并通过实时 OPAL-RT 4510 进行验证。
