中文摘要:

      2020年冬天，湖南、江西、浙江等多地出现“限电”现象，一方面是由于电力需求过大，另一方面是由于电力供给结构不合理，而发展工业用户侧储能可在一定程度上避免“限电”问题。在工业用户侧配置储能不但可以缓解电网供电紧张的问题，促进可再生能源的消纳，还可以降低工业用户的用电成本，获得峰谷价差收益。首先研究了江苏省工业用户侧储能的发展情况及促进储能发展的相关政策；然后参考江苏省现行工业用户电价和调峰辅助服务政策，研究了工业用户侧配置锂离子电池和全钒液流电池储能的经济性；最后，针对江苏工业用户侧储能的发展提供了一些建议。

英文摘要:

      Hunan, Jiangxi and Zhejiang province have experienced“power curtailment”in the winter of 2020. On the one hand,it is due to excessive power demand. On the other hand, due to the unreasonable power supply structure, and the development of industrial user-side energy storage can help solve the issue of“power curtailment”to a certain extent. The deployment of energy storage on the industrial user side can not only alleviate the problem of grid power supply shortage, promote the consumption of renewable energy, but also reduce the industrial user’s electricity cost and obtain the peak-to-valley price yield. The development of user-side energy storage in Jiangsu province and related policies to promote the development of energy storage are studied firstly. Then, referring to the current industrial consumer electricity prices and peak shaving auxiliary service policies in Jiangsu province, the economics of battery energy storage of industrial user-side configuration of lithium-ion battery and full vanadium liquid flow battery are studied. Finally, some suggestions are provided for the development of user-side energy storage in Jiangsu province.
