【摘要】 针对目前风电消纳局限于电源端和系统侧的研究现状,提出了一种基于负荷端的风电消纳新方法,采用中功率风电机组,在负荷端单机并入配电网,对负荷形成风网互补的供电模式。设计了系统的基本构架,采用Matlab建立了负荷端单机风网互补方式运行模型。考虑到负载波动影响,带动分批投入的6台电动机负载。建立了典型风速和周期性正弦风速等效模型,分别得到风力发电机的输出曲线、负荷运行曲线及电网配送电曲线。仿真结果证明该方法可实现风能最大化利用,并有效降低了配电网损,从而为解决风电消纳问题提供了一种新的运行模式和思路。更多还原

【Abstract】 Based on current the research status that the wind power accommodation is limited to the power terminal and the system side, a new research idea based on the load end wind power accommodation is proposed. The medium-power wind turbine is applied into the distribution network of the load side. Using MATLAB as the load PC network complementary operation model, a standard wind equivalent model is established, by which the wind turbine output curve, load curve and power curve are obtained. The results prove that this method can make full use of the wind energy and reduce the distribution loss, which provides a new operation mode to solve the problem of wind power accommodation.更多还原
