摘要
针对分散式风电弃风严重、低电压过渡能力弱等问题,以提升其消纳能力及绿色友好并网为目标,提出风氢耦合系统模型及控制策略。构造1种电解槽和燃料电池集结于直流母线的结构,建立直驱风机、电解槽及燃料电池数学模型,基于能量协调控制策略,在MATLAB/Simulink中搭建风氢耦合混合系统模型,对系统正常运行及故障工况进行仿真分析,结果证明系统能够很好地提升分散式风电消纳及低电压过渡能力。
For the problems of distributed wind power abandonment and weak low voltage ride-through,the model of wind-hydrogen coupling system and control strategy are proposed targeted at improving consumption capacity of the distributed wind power and green friendly integration.Constructing a structure with an electrolytic cell and fuel cell assembled in the DC bus,a mathematical model of direct drive fan,electrolyzer and fuel cell is established.Based on the control strategy of energy coordination,a wind-hydrogen coupled hybrid system model is built in MATLAB/Simulink.The simulation and analysis of the operation and fault conditions show that the system can improve the distributed wind power consumption and low voltage ride-through capacity.
