摘　　要：考虑到综合能源系统(integrated energy system,IES)的经济性和节能性,以及储氢及电蓄热系统在电力调峰方面的重要作用,设计了一种包含储氢及电蓄热系统的园区综合能源系统,并提出系统的容量配置方法及优化调度策略。首先提出系统结构,并建立关键设备的数学模型;然后以系统综合能量成本最小为优化目标,提出系统优化设计模型;最后运用粒子群算法(partide swarm optimization,PSO)与Gurobi结合的双层求解方法对优化模型进行求解。算例结果表明,所提园区综合能源系统能够将电-气-冷-热联合规划,合理分配资源;与园区原有供能系统相比,储氢及电蓄热系统可降低电、热、冷的用能成本,提高系统的经济性,具备在需求侧推广的潜能;综合能源系统可有效利用低谷期电能,具备较强的移峰填谷能力。Considering the advantages of integrated energy systems(IES)in economy and energy saving,and the important role of hydro-gen storage and electric heat storage systems in power peaking,An IES for parks that includes hydrogen storage and electric heat storage systems is designed,and the capacity configuration method and optimal dispatch strategy are proposed.Firstly,the basic architecture of the system is established,and the mathematical model is established for the key equipment.Then establish a system optimization design model,in which the minimum system integrated energy cost is the optimization target.Finally,the optimization design model is solved by the bi-level solution combining particle swarm optimization(PSO)and Gurobi.Simulation results indicated that the IES designed with the proposed method can plan electricity,hydrogen,cooling and heating together to allocate resources rationally.Compared with the original energy supply system in the park,IES can reduce the energy cost of electricity,heating and cooling,improve the economics of the system,and have the potential to be promoted on the demand side.The hydrogen storage and electric heat storage system can effectively utilize the electricity in the power system valley load period,and has a strong ability to shift peaks and fill the valley.
