| 中文摘要:针对光伏的不确定性、波动性与反调峰性对配电网稳定运行造成巨大冲击，而大幅增加配网调峰压力的问题，提出了光伏-氢储能辅助调峰的双层优化配置模型。基于光伏波动量对配网的影响，将原始光伏出力曲线分解为调峰分量与平抑波动分量；结合氢储能运行特性，配置用于调峰与平抑波动的储能容量，构建计及氢储能工作特性的储能系统运行策略；以系统运维成本、碳排放成本、弃光惩罚为优化目标，建立光伏-氢储能辅助调峰的配电网氢储能优化配置模型，并进行算例分析。结果表明，所提出的优化配置方案可有效降低光伏波动对配网的影响，缩减配网的运行成本，提升其运行经济性与稳定性。 |

| Abstract:Focusing on the uncertainty， volatility and anti-peaking of photovoltaic which have significant impacts on the stable operation of the distribution network and greatly increase the peak load regulation pressure of the distribution network， a bi-level optimal configuration model of photovoltaic-hydrogen energy storage assisted peak regulation is proposed in this paper. Based on the influence of photovoltaic fluctuations on the distribution network， the original photovoltaic output curve is decomposed into the peak-shaving component and the smoothing fluctuation component. Based on the operation characteristics of hydrogen energy storage， the energy storage capacity for peak regulation and fluctuation suppression is configured， and the operation strategy of energy storage system considering the operation characteristics of hydrogen energy storage is constructed. Taking the system operation and maintenance cost， carbon emission cost and light abandonment penalty as the optimization objectives， the optimal configuration model of hydrogen energy storage in the distribution network assisted by photovoltaic-hydrogen energy storage is established， and the example analysis is carried out. The results show that the proposed optimal configuration scheme can effectively reduce the impact of photovoltaic fluctuations on the distribution network， reduce the operation cost of the distribution network， and improve its operation economy and stability. |
