摘要：
In order to promote the comprehensive utilization of flexible resource in energy system containing hydrogen，aiming at the problem of photovoltaic-energy storage-hydrogen production integrated system respon-sing to the dispatch instruction，a real-time energy management strategy for photovoltaic-energy storage-hydro‑ gen production integrated system considering generalized energy storage participating in flexible response is proposed. The refined modeling of generalized energy storage such as battery energy storage and electrolytic hydrogen production load in the photovoltaic-energy storage-hydrogen production integrated system is carried out，and a virtual energy storage model of electrolytic hydrogen production considering the electric-thermal-flow coupling relationship is introduced into the integrated system model. An intra-day and real-time two-level energy management strategy is established by optimizing the output of flexible resource in the integrated system，which considers the maximum benefit while satisfing the scheduling plan requirement in the energy management optimizaiton level，and realizes the optimization of initial and final states of charge for battery energy storage. The real-time feedback correction of system power fluctuation is carried out to ensure the power balance in the integrated system. The example and simulation results verify the positive effect of the proposed strategy in improving the operation economy benefit and renewable energy accommodation. © 2024 Electric Power Automation Equipment Press.
