| 中文摘要: |
| 建立高渗透率可再生能源系统是实现碳中和的必由之路，然而可再生能源出力具有波动性与季节性，为实现可再生能源的长时间尺度规划，以最小年化成本为目标，将制-储-用氢环节纳入可再生能源规划决策，建立了全年时序生产模拟的基于氢储能的可再生能源系统模型，将系统成本问题与运行模拟问题统一到规划层面。为验证基于氢储能的可再生能源系统的优越性，对比基于电池储能的可再生能源系统的年化成本；验证具有不同风光资源地区的适用性，对比具有不同风光资源特性地区规划结果。最后，引入可调度能源价格与电解槽设备输入功率变化量对系统参数的灵敏度分析，并通过算例表明在两地区氢储能系统实现电能的季节性存储，虽然在转化效率上具有劣势，但是在经济性与弃电率上具有明显优势。 |

| Building high- penetration renewable energy systems is the only way to achieve carbon neutrality, but the output of renewable energy is fluctuating and seasonal. In order to realize the long-term planning of renewable energy, with the goal of minimizing the annualized cost, the links of production-storage-hydrogen use are included in the planning and decision-making of renewable energy, and a comprehensive system has been established.The hydrogen energy storage-based renewable energy system model for annual time series production simulation unifies the system cost problem and the operation simulation problem to the planning level. In order to verify the superiority of the renewable energy system based on hydrogen energy storage, the annualized cost of the renewable energy system based on battery energy storage is compared. In order to verify the applicability of areas with different wind and solar resources, the planning results of areas with different wind and wind resources characteristics are compared. Finally,the sensitivity analysis of the dispatchable energy price and the input power change of the electrolyzer equipment to the system parameters is introduced. The calculation example shows that the seasonal storage of electric energy in the hydrogen energy storage systems in the two regions has obvious advantages in terms of economy and curtailment rate, although it has disadvantages in comprehensive efficiency. |
