摘要

风电功率爬坡事件越来越影响风力机在电网中的运行，随之而来的爬坡事件预测问题成为国内外新的研究热点。综述了风电功率爬坡事件的研究背景、定义和特征，建立了考虑频率偏差量的含风力机的准稳态潮流计算模型，将频率偏差量和滑差修正量引入雅可比矩阵中进行含风力机的潮流计算，采用两种频率偏差指标（PRESF指标和APRESF指标）对爬坡事件进行预测。将所述预测模型应用于5节点和10机39节点系统进行算例仿真，对结果的对比分析验证了该方法的有效性。

Abstract

Wind power ramp events have more and more influence on the wind turbine operation in the power system.Ramp events prediction becomes a new research topic at home and abroad.Research background，definitions and characteristics are summarized with respect to wind power ramp events.By considering frequency deviation values，a quasi-steady-state power flow calculation model is established including wind turbines.Frequency deviation value and slip correction value are introduced into the Jacobi matrix to calculate the power flow.Two types of indices，PRESF and APRESF，are adopted to forecast the ramp events.The proposed forecasting model is applied to 5-node system and 10-machine 39-node system for the validation simulation.Results verify the method with comparison and analysis.
