There are variety of applications of battery energy storage system(battery energy storage system, BESS) used in the combined system of wind power and energy storage, and improving grid-connected wind power operation ability under dispatch by using battery energy storage system is currently one of the research focus. Based on forecast and historical operation data of a wind farm in northern China, this article reports an analysis on the wind farm forecast data to obtain the forecast error probability distribution characteristics by using an evaluation method combining the prediction error indicators and wind farm forecast assessment indicators. A battery energy storage system is then proposed to improve the ability to track wind power schedule output, followed by statistical analyses and quantification of the scope of racking schedule output. Finally, simulation verifications are performed of the effectiveness and viability of the control strategy for improving the ability of wind power tracking schedule output.
