基于典型地区大工业用户各地区分时电价的情况和典型储能方案实际造价,详细分析工业用户分布式电化学储能系统在峰谷套利盈利模式下的经济性.在此基础上,建立了用户侧储能系统经济性分析模型,对比不同的电池选型、充放电运行策略在用户侧电池储能系统的经济性,并进行了关键参数灵敏度分析.分析结果表明以目前的储能系统成本,用户侧电池储能系统在江苏、上海、深圳等峰谷电价差较大地区具有投资经济性.预计其成本2020年可降至全国大部分地区大规模商业化推广应用水平.%Based on the time-of-use electricity price of large industrial users in typical areas and the actual cost of energy storage system, this paper analyzed the economy of distributed electrochemical energy storage system of industrial users in the peak-valley arbitrage profit model in detail. On this basis, the economic analysis model of the user-side energy storage system was established, and the economy of different battery selection, charge-discharge operation strategy in the user-side battery energy storage system was compared, and the sensitivity analysis of the key parameters was carried out. The analysis results show that the current energy storage system is economical in Jiangsu,Shanghai,Shenzhen and other regions with large peak-valley electricity price difference. Its cost is expected to be reduced to the level of a large scale commercial application in most parts of the country by 2020.
