摘　　要：结合绿色、高效的氢储能方式,提出了光氢混合发电系统功率协调控制策略。氢储能主要包括电解槽、储氢罐和质子交换膜燃料电池,考虑到实际燃料电池和电解槽自身动态响应速度慢的特性,采用功率密度高、暂态性能好的超级电容器来弥补氢储能装置动态响应过程中的不平衡功率。光伏、超级电容器及氢储能各单元通过DC/DC变换器及功率协调控制策略,汇集与分配电能到直流母线,利用DC/AC并网逆变器接入交流系统。通过算例仿真分析,验证了所提协调控制的正确性和有效性。By referring to the green, efficient hydrogen storage mode, a power coordinated control of photovoltaic and hydrogen hybrid power generation system is proposed. Hydrogen storage includes the electrolyzer, hydrogen storage tank and proton exchange membrane fuel ceils （PEMFC）. Considering the slow dynamic response characteristics of PEMFC and eleetrolyzer, a supercapacitor with high power density and good transient performance is used to make up for the power imbalance of the hydrogen energy storage device during its dynamic response. Photovoltaic, supercapacitors and hydrogen storage units collect and allocate electric energy to the DC bus through the DC/DC converter and power coordinated control strategy, and connect to the AC system by using DC/AC inverter. Simulation analysis shows that the proposed power coordinated control storage is correct and effective.
