摘要
针对风力发电系统面临能量输出不稳定、低电压穿越能力弱等问题,提出将氢储能系统安装在双馈风力发电机组变流器中间直流母线处,构建了基于氢储能技术的双馈风力发电系统的基本架构。进一步,利用宏观能量表示法(EMR)建立了基于氢储能技术的双馈风力发电系统的模型,并基于EMR反转规则建立了系统的最大控制框架。在此基础上,基于MATLAB/Simulink搭建了基于氢储能技术的双馈风力发电系统的仿真模型,并进行了仿真验证,结果表明了氢储能系统能够平抑风电输出功率波动及提高系统的低电压穿越能力,同时验证了所建EMR模型的正确性。
We established an architecture of doubly-fed wind power generation system with hydrogen energy storage （HES） devices installed at the DC bus to solve problem that output instability of wind power generation system and low ability of LVRT. Moreover, we established a model of doubly-fed wind power generation system based on hydrogen energy storage technology on energetic macroscopic representation（EMR）, and built a maximal control framework of the system on the EMR rules of inversion. Therefore, simulation verification is conducted through MATLAB/Simulink and the results indicate that hydrogen energy storage system can not only adjust the output power of doubly-fed wind power generator but also improve the ability of LVRT, and the validity of the model is verified at the same time.
