风电氢能系统的耦合机制与方法研究

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.

我国风电在局部地区的快速发展，给电网的运行与稳定带来了较大挑战，如何改善风电场的电源特性，提高风电的品质和风电场的综合效益，成为风电可持续发展的重要研究课题。本项目提出在风电场配置电解制氢系统，通过调节该系统的运行状态主动调节风电有功功率变化和电力系统的调峰调频。新疆是我国"西气东输"管道的源头，如果能将电解制氢过程与风电的运行状态和电力系统状态有机耦合，产氢后加压储存运输，作为燃料使用，对于提高风电品质和风电场的综合经济效益，具有重要的理论和现实意义。项目进行风电氢能耦合系统的特性分析与建模，提出了基于模型预测控制耦合控制方法，进行了系统容量配置和效益评估等研究，并通过新疆地区的典型风电场进行案例分析。本项目的研究，对于有效发挥风电氢能之间的耦合与调节作用，促进风电又好又快发展提供理论和技术基础。
