Abstract

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.

Key words: wind power, flow battery, energy storage, revenue model, economic analysis
