摘要: 光伏发电的间歇性、随机性以及波动性一直是制约其大规模发展的主要原因之一。该文提出了基于氢储能装置的混合并网发电系统及其控制策略。混合系统中,氢储能装置主要元件包括电解槽、储氢罐和质子交换膜燃料电池(proton exchange membrane fuel cell, PEMFC)等,各单元通过功率变换器汇集到直流母线,最后经由逆变器与交流电网相连。考虑到储氢罐压力上下限约束及燃料电池和电解槽自身额定出力的限制,同时引入功率密度高的超级电容器作为备用以确保连续可靠供电以及对太阳能资源的最大利用。在满足各元件约束条件以及氢储能装置启动优先级高于超级电容器的前提下,提出了6种运行状态下的功率协调控制策略。通过仿真分析,验证了该协调控制策略的有效性。

Abstract: Intermittent, randomness and volatility of photovoltaic (PV) power generation, has been one of the main reasons restricting its large-scale development. This paper uses pure green hydrogen energy storage devices with high energy density to improve the reliability of power supply of PV array. In hybrid systems, hydrogen energy storage devices comprise electrolyzer, hydrogen storage tank and a proton exchange membrane fuel cell (PEMFC), etc., for each cell by bringing together the power converters to the DC bus, and finally are connected via an inverter from the AC grid. Taking into account the constraints on the limit of pressure hydrogen storage tank, the electrolyzer and the rated output of fuel cell, this paper introduces high power density supercapacitors as a backup to ensure continuous and reliable power supply and the maximum use of solar energy resources. Under the premise of satisfying the constraint conditions of each component and hydrogen energy storage device starting a higher priority than supercapacitor, this paper proposes power coordination control strategy under six kinds of operation modes, whose effectiveness is verified by simulation analysis.

Key words: grid-connected photovoltaic, electrolyzer, fuel cell, supercapacitor
