    摘要:

    氢相较于电更易存储的属性使其可在高比例可再生能源消纳中发挥重要作用。本文着重研究了不同时间尺度氢需求(柔性氢需求)对区域综合能源系统运行优化的影响。在区域综合能源系统建模中,重点考虑了可再生能源出力不确定性、需求侧响应和柔性氢需求。通过小时级年电力负荷需求和光伏出力数据,以最小化系统年运行费用为目标,研究了不同光伏消纳水平下柔性氢需求对区域综合能源系统优化运行的影响。结果表明,随着氢需求时间尺度逐渐增大(终端存储能力逐渐增强),系统经济性逐渐提高,并在设备运行、与上级电网交易和需求侧响应等方面效果显著。

    Abstract:

    Compared with electricity, hydrogen is easier to store and can play an important role in the high renewable energy integration. This paper focuses on the influence of hydrogen demand (flexible hydrogen demand) at different time scales on the optimization of regional integrated energy systems. In the modelling of regional integrated energy systems, the uncertainty of renewable energy output, demand-side response and flexible hydrogen demand are mainly considered. Based on hourly annual electricity load demand and photovoltaic output data, we studied the impact of hydrogen demand at different time scales under different photovoltaic penetration levels on the optimal dis-patch of regional integrated energy systems, with the goal of minimizing the annual operating cost of the system. The results show that as the time scale of hydrogen demand gradually increases (the storage capacity of the terminal gradually increases), the system economy gradually improves, and the effect is significant in terms of equipment operation, transaction with the upper-level grid, and demand-side response.
