摘　　要：随着新能源大规模并网,其间歇性和波动性问题日益突出。为缓解新能源间歇性与波动性问题,提升新能源利用率,该文结合储能电池、熔盐储热系统及电解水制氢系统的调节特性,提出了一种电/热/氢混合储能系统容量优化配置方法。场景构建阶段,考虑总净负荷最小以优化新能源装机容量,并基于K-means聚类和累计波动量指标选取典型日数据作为混合储能系统容量优化配置的基础参数;频繁充放电会影响电池寿命,为避免规划结果偏于乐观,提出了计及电池寿命并以日综合净收益最大为目标的电/热/氢混合储能系统容量优化配置模型;考虑需求侧响应,通过调整可时移负荷以减少发电与需求侧的不匹配。算例基于我国西北某地区风、光、荷数据进行仿真测试,结果表明,电/热/氢混合储能系统能兼顾系统可靠性、经济性和提升新能源利用率;考虑电池寿命,可避免规划结果偏于乐观并确保系统经济最优化;考虑需求侧响应,可提升系统经济效益,验证了模型的有效性。With the large-scale integration of new energy,its intermittent and volatility problems have become increasingly prominent.To alleviate the intermittency and volatility of new energy and improve the utilization rate of new energy,this paper proposes a capacity optimization configuration method of battery,thermal,and hydrogen hybrid energy storage system based on the regulation characteristics of energy storage battery,molten salt thermal energy storage system,and electrolytic water hydrogen production system.In the scenario construction stage,the minimum total net load is considered to optimize the installed capacity of new energy,and the typical daily data are selected as the basic parameters for the optimal configuration of hybrid energy storage system capacity based on K-means clustering and cumulative fluctuation index.Frequent charging and discharging will affect the battery life.To avoid optimistic planning results,a capacity optimization configuration model of a battery,thermal,and hydrogen hybrid energy storage system is proposed,which considers battery life and aims to maximize daily comprehensive net income.Considering the demand side response,adjusting the time-shiftable load reduces the mismatch between the power generation and the demand side.The simulation test is carried out based on wind,light,and load data in a certain area of northwest China.The results show that the battery,thermal,and hydrogen hybrid energy storage system can consider the system reliability and economy and improve the utilization rate of new energy.Considering the battery life,the planning results can be avoided to be optimistic,and the economic optimization of the system can be ensured.Considering the demand side response,the economic benefit of the system can be improved,and the model's effectiveness is verified.
