【摘要】 氢能能量密度高，具有良好的储能能力，将储氢应用于园区综合能源系统可有效提高其经济性。为此，针对含储氢结构的园区综合能源系统进行了优化配置研究，首先以储氢替代储电的形式构建了含储氢结构的园区综合能源系统，以系统全寿命周期等年值为容量配置层目标函数，系统年运行成本为优化运行层目标函数，在能量平衡和设备出力等约束条件下，建立了相应的优化配置模型，并采用粒子群算法与CPLEX求解器相结合的双层优化算法进行求解，最后对园区算例的设备容量、运行方式、系统性能和经济性进行分析。分析表明，建立的含储氢结构的园区综合能源系统能实时可靠地满足用户能源需求，且相较于含储电结构的园区综合能源系统，两者性能大致相同，但前者经济效果更明显，进而验证了所提方法的可行性。更多还原

【Abstract】 Since hydrogen energy is of high energy density and good energy storage capacity,its application to an integrated energy system for an industrial park can effectively improve the economy of the system.A study on the optimal configuration of integrated energy systems for parks with hydrogen storage devices is made. Firstly,electricity storage devices for the system are replaces by hydrogen storage devices.Then,the system takes the uniform annual value of its whole-life-cycle cost as the objective function of the capacity configuration layer,and its annual operating cost as the objective function of the optimal operating layer.Under the constraints on energy balance and equipment outputs,the corresponding model of the optimal configuration is established. The bi-level optimization algorithm that integrates particle swarm algorithm and CPLEX solver is used to solve the model. Finally,the equipment capacities,operation mode,system performance and economy of the power system for an industrial park are analyzed.The analysis results shows that the scheme of integrated energy systems for parks with hydrogen storage systems can meet users’ real-time energy demand reliably.Comparing the power system with hydrogen storage devices and the one with electricity storage devices,their performances are roughly the same,but the former one is obviously more economic,which proves the practicability of the suggested method.更多还原
