摘　　要：为实现混合储能模型结构和能量形式的统一及在优化运行研究中考虑储能的实时能量状态,提出一种基于等效氢耗混合储能模型及荷能状态的园区优化运行方法。首先,以等效氢耗度量方法为理论基础,建立基于等效氢耗的混合储能单元模型,实现混合储能单元模型结构及能量形式的统一。类比于传统储能模型的荷电状态及容量,提出荷能状态与载能量的概念,表征所提模型中储能的实时能量状态。在此基础上提出充放调节成本,实现对混合储能单元的灵活性调度;然后,建立考虑荷能状态的混合储能园区优化运行模型,搭建能量平衡约束以描述园区内多能量流的能量流动过程;最后,通过仿真模拟证明所提优化运行方法能够充分调用灵活性资源,使园区的总成本降低5.5%、弃电量降低20.38%、切负荷量降低33.5%,提高园区运行的经济性及灵活性。To achieve the unification of hybrid energy storage model structures and energy forms,while integrating real-time energy state considerations into operational optimization research,a park-level optimized operation method was proposed based on an equivalent hydrogen consumption hybrid energy storage model and state of energy(SOE).First,grounded in the theoretical framework of equivalent hydrogen consumption measurement,a hybrid energy storage unit model was established that unifies both structural design and energy form representation.Drawing parallels to traditional energy storage metrics like state of charge(SOC)and capacity,the concepts of state of energy and energy capacity were introduced to characterize real-time energy dynamics in the proposed model.Building on this foundation,charge/discharge adjustment costs were formulated to enable flexible dispatch of hybrid energy storage units.Subsequently,an SOE-incorporated hybrid energy storage park optimization model was developed,featuring energy balance constraints to map multi-energy flow processes within the park.Simulation results verify that the proposed method effectively mobilizes flexible resources,achieving a 5.5%reduction in total operational costs,a 20.38%decrease in renewable curtailment,and a 33.5%mitigation of load shedding,thereby significantly enhancing the park’s economic efficiency and operational flexibility.
