基于燃气内燃机提出了一种利用可再生能源的有蓄能的多能互补耦合系统。利用混合整数线性规划方法，构建了一种系统优化配置模型，可实现包含蓄能装置在内的设备运行策略、种类、台数及容量的同步优化，并给出了经济、热力和环境影响等系统综合评价指标。以广州市某典型医院为研究对象开展了系统优化配置与综合评价研究。研究结果验证了模型的准确性与有效性，并显示蓄能装置引入后的能力：可以减小系统内其它制冷、制热设备的容量；各机组运行不再完全受负荷的限制，系统运行更加灵活；对系统节能减排性能影响不大，会提高系统经济性。

Based on gas engine,a multienergy complementary system with storage utilizing renewable energy resources is proposed.The mixed integer linear programming method is applied to construct a system optimizing model,which can help achieve simultaneous optimization of the type,number,capacity and operation rules of equipment (including storage device),and to give various evaluation indices in economy,thermal performance and environmental impact.The study on configuration optimization and comprehensive evaluation is carried out in a typical hospital in Guangzhou.The results verify the accuracy and validity of the proposed model,and indicate that after the storage device is introduced,the capacity of other heating and cooling equipment can be decreased,and the operation of each unit can be partly freed from the constraint of heating and cooling load,making the system operation more flexible.Meanwhile,the system economy can be improved without influencing the performance of energy saving and emissions reduction.
