基于参数自调节的电氢耦合系统调频控制策略研究
Research on Frequency Modulation Control Strategy of Electric-Hydrogen Coupling System Based on Parameter Self-regulation
摘要
Abstract
In view of frequency control of Hydrogen energy storage system containing proton exchange membrane fu-el cell(PEMFC),a kind of system frequency control strategy based on virtual parameter self-regulation is proposed in order to improve the frequency stability of Hydrogen energy storage system.The electric-Hydrogen coupling system is supported by PEMFC,assisted by photovoltaic(PV)and energy storage battery,and the power is supplied to the sys-tem integrated load through a mixture of PEMFC,PV and energy storage battery.Through mathematical model con-struction,the dynamic response changes of PEMFC and energy storage battery are observed after a small disturbance occurs in the system,and the virtual control parameters are changed to adjust the power distribution in the system.Due to different dynamic response times of the PEMFC and the storage battery,different control strategies are adopt-ed for the PEMFC and the storage battery,which are specifically embodied in the sag control of the PEMFC and the inertia control of the storage battery in order to achieve the purpose of maintaining the frequency of the system in the normal range of small fluctuations and tend to be stable.Finally,the effectiveness and superiority of the proposed strategy is verified by setting up a model through MATLAB/Simulink simulation platform.关键词
