摘要

现在，电力制氢（P2H）系统成为解决风能不确定性和风电弃风的重要解决方案。本文主要从控制角度研究P2H效率的提高。首先，建立了基于风能的P2H模型，通过灰色关联分析（GRA）对影响制氢效率的因素进行了定量和定性分析。研究发现，与湍流强度、电解水温和储能容量相比，直流母线电压和平均风速对制氢效率的影响更大。在此基础上，提出了一种考虑高敏感因素的改进电压功率下降控制策略。与传统的电压功率控制策略相比，所提出的控制策略可以提高制氢效率和储能系统的荷电状态（SOC）。通过MATLAB/Simulink实验验证了所提控制策略的有效性。

An improved voltage-power control strategy of wind power-to-hydrogen systems considering hydrogen high sensitivity factors

Now a power-to-hydrogen (P2H) system becomes an important solution to address wind energy uncertainty and wind power curtailment. This paper is focused on the P2H efficiency enhancement from the control perspective. First, a wind energy based P2H model is presented, where the impact factors on the hydrogen production efficiency are quantitatively and qualitatively analyzed through grey relational analysis (GRA). It is found that compared with the turbulence intensity, electrolytic water temperature, and energy storage capacity, the DC bus voltage and average wind speed produce higher influence on hydrogen production efficiency. Based on such findings, an improved voltage-power droop control strategy considering the highly sensitive factors is proposed. Compared with traditional voltage-power control strategy, the proposed control strategy can improve the hydrogen production efficiency along with the state of charge (SOC) of the energy storage system. The effectiveness of the proposed control strategy is verified with MATLAB/Simulink studies.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
