| 摘要: |
| 燃料电池是氢储能中的重要组成部分，其运行效率对含氢储能的综合系统的经济性有较大影响。为此，提出考虑燃料电池变工况特性的风-光-氢综合能源系统优化调度方法。通过分析燃料电池输出功率和运行效率间的关系，建立燃料电池变工况条件下运行效率的分段线性化模型。提出考虑燃料电池的变工况效率特性的多模块输出功率协同优化策略和燃料电池多模块工作协同策略，从而提升燃料电池总体运行效率和各模块使用寿命。基于此，以风-光-氢综合能源系统优化调度为例，验证了所提优化运行策略的有效性。 |

| Abstract: |
| Fuel cell is an important part of hydrogen energy storage, its operation efficiency has greater influence on integrated system containing hydrogen energy storage. Therefore, an optimal scheduling method of wind-solar-hydrogen integrated energy system considering variable operating condition of fuel cell is proposed. By analyzing the relationship between output power of fuel cell and operation efficiency, the segmented linearized model of operation efficiency for fuel cell under variable operating conditions is established. A multi-module output power synergistic optimization strategy and a multi-module work synergistic strategy for fuel cell are proposed, which considers the efficiency characteristics of fuel cell under variable operating conditions, so that improving the overall operation efficiency of the fuel cell and the service life of each module. On this basis, the optimal scheduling of the wind-solar-hydrogen integrated energy system is taken as an example, and the effectiveness of the proposed optimal operation strategy is verified. |
