| Popis: | Hydrogen production by wind power is a full-cycle, zero-carbon emission hydrogen production method. However, the random and intermittent nature of wind energy leads to instability in the grid-connected power of wind power. Hence, this paper proposes an intraday energy management strategy for wind-hydrogen coupled systems to achieve flexible operation. Firstly, the AHP and EWM were used to optimise the capacity ratios of the hybrid electrolyzer to improve the objectivity of the hybrid electrolyser selection. Then, a wind-hydrogen coupled system model including a wind power system, hybrid electrolyser hydrogen generation system, and hydrogen fuel cell power system is constructed. Energy management strategies for six operating conditions are proposed to combine the operating characteristics of each system, which solves the problem of poor wind power consumption due to the fluctuation of wind power effectively. Finally, the effectiveness and feasibility of the proposed control strategy are verified based on actual wind farm data. |
