摘要:

针对电解槽额定功率的合理选择是风电制氢的关键问题,提出一种基于时序生产模拟考虑弃风率的电解槽额定功率边界计算方法。通过电解槽出力与额定功率的关系,利用时序生产模拟计算出弃风率,进而得出电解槽额定功率与弃风率的关系,用国家规定的弃风率边界计算出电解槽额定功率边界。为使选择的典型风电出力日可以代表该地区最恶劣情况,将不同天相同时段的风电波动量最大值和最小值分别作为典型风电出力日时段的风电出力的增加量和减少量。最后利用和田200 MW风电场风电出力数据进行验证,结果表明为风电场配备电解槽可以大幅降低弃风,随着弃风率增加,电解槽额定功率降低。

Abstract:

The reasonable selection of rated power of electrolyzer is the key problem of hydrogen production by wind power.Aiming at this problem,this paper proposes a calculation method of rated power boundary of electrolyzer based on time series production simulation and considering wind rejection rate.Through the relationship between the output and rated power of the electrolytic cell,the air abandonment rate can be calculated by using the time series production simulation,and then the relationship between the rated power and the air abandonment rate of the electrolytic cell can be obtained.The rated power boundary of the electrolytic cell can be calculated by using the air abandonment rate boundary specified by the state.In order to make the selected typical wind power output day represent the worst situation in the region,the maximum and minimum values of wind wave momentum in the same period of different days are taken as the increase and decrease of wind power output in this period of typical wind power output day.Finally,the above model is verified by using the wind power output data of Hetian 200 MW wind farm.The results show that equipped with electrolyzer for wind farm can greatly reduce the abandoned wind,and the rated power of electrolyzer decreases with the increase of abandoned wind rate.

Key words: hydrogen energy, production simulation, wind power generation, typical day
