摘要：

通过对西北地区某200 MW风场实际运行情况分析，根据液流电池储能技术特征，本工作研究了风场配置液流电池储能运行模式。建立了储能收益模型，评估并对比了风场配置不同规模的液流电池储能系统所获得的收益，获得了较优的储能配置规模。分析结果显示，在选定风场条件下，在小规模移峰和跟踪计划出力运行模式下，5 MW/10 MW·h的液流电池储能规模是最适合方案，能够实现跟踪计划出力、减少弃风和适度移峰的功能，最大化的发挥该配置条件下液流电池储能的作用，典型的投资回收期小于8年，收益可观。

Abstract:

Based on the analysis of the actual operation of the 200 MW wind farm in the northwest in China and the technical features of flow battery energy storage technology, the wind farm is configured with the flow battery energy storage operation mode, and an energy storage revenue model is established. By comparing the gains obtained by deploying flow battery energy storage systems of different sizes in the wind farm, an optimum energy storage scale is obtained. Under the selected wind field conditions, in small scale peak shifting and tracking plan output operation mode, the 5 MW/10 MW·h flow battery energy storage scale is the best solution, which can achieve the purpose of tracking plan output, reduce wind abandonment, and moderately peak shifting, and to maximize the energy storage value. The energy storage station investment payback period is less than 8 years.
