摘要
Abstract
With the increasing scale of new energy integration,the flexibility of the power grid is decreasing,especially the ability of frequency modulation is becoming more and more prominent.The large-scale electrolytic hydrogen production system has emerged as a potential frequency modulation resource for the power system because of its fast response speed and large power level.To investigate the ability and effectiveness of large-scale electrolytic hydrogen production system participating in power grid frequency modulation,this paper first analyzes the electrical energy demand of electrolyzer to determine the topology of hydrogen production power supply.Subsequently,the equivalent mathematical model of hydrogen production power supply and the mathematical model of electrolyzer are derived.Secondly,the principle of proportional droop control is analyzed to develop the control strategy for large-scale electrolytic hydrogen production system participating in primary frequency modulation of the power system.Finally,the simulation verification of large-scale electrolytic hydrogen production system participating in power system frequency modulation is carried out.The simulation results indicate that the large-scale hydrogen production system participating in the primary frequency modulation of the power system can not only increase the lowest frequency after disturbance by 0.04 Hz,but also reduce the frequency deviation in the dynamic process.Therefore,the large-scale electrolytic hydrogen production system has the ability to provide active support for the power grid and suppress the frequency fluctuations of the power system.关键词
