严寒地区消纳风电的热泵供热系统设计研究

Design and Research of Wind Power Heat Pump System in Severe Cold Region

选取辽宁沈阳地区的住宅小区建立以消纳风电为核心的风电热泵供暖系统。通过建筑能耗模拟软件计算住宅小区全年的能耗,将模拟的建筑空调能耗和风力发电机的月累计发电量相对比,设计出保障生活住宅冷热需求的风电供冷供热系统的方案。同时对系统方案进行模拟计算,将蓄电系统的结余电量最小值为目标函数通过MATLAB优化工具箱进行线性优化。可以得到在风电机组的最佳装机容量为3 MW时,住宅小区所设风电供冷供热系统蓄电状态下的全年储能运行曲线以及锂电池储能系统对应的配置容量。

This paper selects residential communities in Shenyang,Liaoning to establish a wind power heat pump heating system with wind power as the core. The annual energy consumption of residential areas by building energy simulation software to calculate the monthly total generating capacity simulation of building energy consumption of air conditioning and wind turbines as opposed to design wind cooling and heating system to protect life needs of residential hot and cold program. Simultaneously,the system scheme is simulated and calculated,and the minimum surplus power of the power storage system is used as the objective function for linear optimization through the MATLAB optimization toolbox. It can be obtained the annual energy storage operation curve and the corresponding configuration capacity of the lithium battery energy storage system when the optimal installed capacity of the wind turbine is 3 MW,the wind power cooling and heating system installed in the residential area under the storage state.
