| 摘 要： | 目的 电池储能电站的建设是未来电网发展的必然趋势，文章旨在研究当前电池技术和峰谷电差政策条件下的电池储能电站的经济效益和运行效益。 方法 以电网侧储能电站为对象出发，分析以经济效益指数为判据的经济效益、以延缓变电站扩容建设为衡量的运行效益。同时，以东莞地区电池储能电站为例，对其直接经济效益、运行效益和其他效益进行分析。 结果 在当前电池技术和峰谷电差政策的状况下，东莞电池储能电站的经济效益总体略有亏损，但考虑到建设储能电站存在的其他方面的运行效益等，发展电池储能电站有小幅盈利。 结论 以东莞地区电池储能电站为例的经济效益及运行效益分析也可以为其他同类型电池储能电站的效益分析提供参考。

| Abstract: | Introduction The construction of battery energy storage power stations is an inevitable trend in the future. The research aims to learn the economic and operational benefits of battery energy storage power stations under the present battery technologies and peak-valley price policy. Method For the grid-side energy storage power stations, the economic benefit index was used as the criterion to measure the economic benefit, and the delayed substation expansion was used to measure the operational benefit. Taking battery energy storage power stations in Dongguan as an example, the direct economic benefits, operational benefits, and other benefits were analyzed. Result The results showed that under the present battery technologies and peak-valley price policy, generally the economic benefits of battery energy storage power stations in Dongguan suffered slight loss. Nevertheless, considering other operational benefits of the construction of energy storage power stations, the development of battery energy storage power stations can produce a small profit. Conclusion The case study of economic and operational benefits of battery energy storage power stations in Dongguan can provide a reference for the benefit analysis of other battery energy storage power stations of the same type. |
