摘　　要：针对太阳能光伏发电技术、需求侧管理(DSM)技术和储能技术提出一种新型太阳能冷库系统。探讨利用冷能储存和光伏发电来减少和转移峰值电力需求、降低电力消耗成本的潜力。建立系统的仿真模型并通过实验进一步修正,结果表明系统在5—8月份基本可节约60%以上的电费,能源节约率最高可达48.38%,相应的电费支付最高可节省65.40%。A new solar cold storage system is proposed for solar photovoltaic power generation technology,demand side management(DSM)and thermal energy storage technology.The aim is to explore the potential of using cold energy storage and off-grid solar photovoltaic power generation to reduce and transfer peak power demand and reduce power consumption costs.The Simulink simulation model of the system is established and further revised by experiments.The results show that the energy saving rate of the new system can reach 48.38%in May-August,while the corresponding electricity bill can save up to 65.40%.Overall,the system can achieve more than 60%of electricity cost savings in May-August.
