玉门地区太阳能储能技术路线对比及选择

Comparison and Selection of Solar Energy Storage Technology Routes in Yumen Area

由于风力变化和昼夜交替,风力和太阳能发电呈现出显著的随机性、间歇性及波动性的特点,导致其与用户相对固定的用电需求难以匹配,因此人们希望找到将电能储存起来的办法,即在电力富余的时候将其存储,在电力短缺的时候再释放出来,以满足供需之间实时平衡的需求。目前应用最广泛的太阳能及对应的储能技术路线,主流为光伏+锂电池储能以及光热熔盐储能技术,而未来只有性能及造价综合优势明显的技术才能走得更远。

Due to the change of wind power and the alternation of day and night,wind power and solar power generation show significant characteristics of randomness,intermittence and volatility,which makes it difficult to match the relatively fixed power demand of users.Therefore,people hope to find a way to store electric energy,that is,to store it when there is surplus and release it when there is shortage,so as to meet the demand of real-time balance between supply and demand.For the most widely used solar energy and the corresponding energy storage technology route,the mainstream is photovoltaic+lithium battery energy storage and photothermal molten salt energy storage technology.Only the technology with obvious comprehensive advantages in performance and cost can go further in the future.
