英文摘要： With the scalable development of wind power recent years in China, especially in northwest China, the stability and reliability operation of power grid has been encountered great challenges. The enhancement ofpower characteristics, power quality and economic is keys for the sustainable development of wind power. This project proposed a novel solution which adds hydrogen electrolyze in wind plant, and adjust the power profile according to the variation of wind power and power systemoperation status. Due to the flexible power regulation of hydrogen system, the frequency regulation and peak shaving can be obtained. In some area such as Xinjiang of China, gas pipeline is ready, and this solution can be effective for wind power quality and economic improvement. The characteristic and model, operation mechanism and control method based on model predictive control (MPC), system capacity plan and benefit analysisfor wind power coupling hydrogen system is conducted in detail in this project. The effectiveness of the theoreticalanalysis and relatively method are verified through a Xinjiang wind plant case study.This research can provide important base for the optimum development of wind power.
