将蓄能装置引入到基于超结构方法的分布式联供系统优化配置混合整数线性规划模型之中,所得模型可实现系统结构和运行同步优化、各设备与蓄能装置同时优化,采用分枝定界法结合单纯形算法实现对模型的求解。通过研究案例,验证了计算模型和求解方法的可行性和有效性。计算结果亦表明,联供系统中引入蓄能装置可以减小系统内其它制冷设备的容量;在分时电价体系下引入蓄能装置可以部分解除冷热负荷与发电机组之间的强耦合关系,使联供系统运行更灵活,并降低供能成本和能耗;在不同的典型日内蓄能装置的优化运行规律不同,取决于电价、负荷需求等。
The energy storage device is introduced into the distributed hybrid system based on superstructure method to optimize the mixed integer linear programming model. The model can be used to synchronously optimize the structure and operation of the system. The devices and energy storage devices are simultaneously optimized. Boundary method combined with simplex algorithm to solve the model. Through the case study, the feasibility and effectiveness of the computational model and the solution method are verified. The calculation results also show that the introduction of energy storage device can reduce the capacity of other refrigeration equipment in the system. Introducing the energy storage device under the time-share electricity price system can partially relieve the strong coupling between the heat load and the generator set, So as to make the operation of cogeneration system more flexible and reduce the energy supply cost and energy consumption. The optimization operation rules of energy storage devices in different typical days depend on the electricity price and load demand.
