风光耦合电解水制储氢技术作为可再生能源与氢能结合的重要路径,在能源转型中展现出巨大潜力。然而,在大规模并网型制氢场站存在功率分配不均的问题以及未充分考虑碱性及质子交换膜电解槽的响应特性差异。基于此,提出风光制氢混合电解槽双层阵列优化调度策略。首先以系统净收益最高为目标,采用多时间尺度优化策略对风光制氢系统进行功率分配;其次考虑碱性及质子交换膜电解槽各机组的制氢效率及动态响应特性差异,对单台碱性-质子交换膜混合电解槽集群阵列进行分配及优化调度。结果表明:基于双层优化策略,并网型风光制储氢系统的新能源上网电量与发电量比例无限接近设定值40%,经过双层策略优化的综合弃电率为1.89%,极大地降低了系统的弃风弃光率,充分应用碱性及质子交换膜电解槽的运行特性,达到对波动性可再生能源的充分利用,提高了制氢系统运行的稳定性及安全性。
As an important path for the combination of renewable energy and hydrogen energy
the technology coupling wind solar power with hydrogen production and storage through water electrolysis has shown great potential in energy transformation. However
large-scale grid-connected hydrogen production stations have problems such as uneven power distribution and insufficient consideration of the differences in response characteristics between alkaline and proton exchange membrane(PEM) electrolyzers. Therefore
this paper proposes an optimized scheduling strategy for the double-layer array of wind-solar hydrogen production hybrid electrolyzers. Firstly
with the goal of maximizing the net income of the system
a multi-time-scale optimization strategy is adopted to allocate the power of the wind and solar hydrogen production system. Secondly
considering the differences in hydrogen production efficiency and dynamic response characteristics between the alkaline and the PEM electrolyzers
optimal scheduling is performed for the array of alkaline and PEM hybrid electrolyzers. As a result
based on the two-layer optimization strategy
the ratio of the on-grid electricity generation to the power generation of the grid-connected wind and solar hydrogen production and storage system is infinitely close to the set value of 40%
and the comprehensive power curtailment rate is 1.89%
which greatly reduces the curtailment rate of wind and solar power in the system. The operational characteristics of the alkaline and PEM electrolyzers are fully utilized to achieve the full utilization of fluctuating renewable energy and enhance the stability and safety of the hydrogen production system operation.
