低谷电储能冷热双供系统分析

Electricity load analysis on a dual heating and cooling system with off-peak thermal energy storage

为有效缓解中国电力峰谷差逐年拉大的趋势,提出低谷电蓄能冷热双供系统进行居民冬季供热和夏季制冷。从夏季与冬季的电网平均用电负荷率分析,当北京市集中供热面积的10%采用冷热双供系统后,夏季电网平均用电负荷率可由80.56%提高至100%,冬季电网平均用电负荷率可由83.10%提高至90%。

A combined heating and refrigeration system（HRS） with off-peak thermal energy storage is proposed for load shift of electrical grids and efficiency enhancement of power generation. We show that the average electricity load rate（AELR） of power grid in Beijing area could be increased from 80.56% to 100% in summer, and from 83.10% up to 90% in winter, if 10% the residential central heating/cooling systems uses the HRS technology.
