摘要
针对传统集群风电有功控制模式中安全裕度偏于保守的问题,基于信息物理系统架构提出了一种面向集群风电的运行断面自适应控制方法.基于风电场功率响应特性,提出了断面裕度动态计算的实现方法.根据断面裕度动态计算结果和风电场的发电状态,动态调整风电场运行方式,实现集群风电与运行断面间的自适应.基于某地区电网实际数据构造的算例表明,所提出的方法在降低断面越限时间33.3%的同时,能减少弃风约21.4%.该方法对提升运行断面传输利用率、降低运行断面越限时间具有促进作用.
Aiming at the problem of conservative safety margin under traditional active power control modes of cluster wind power,an adaptive section margin control method for cluster wind power based on a cyber-physics system(CPS)architecture was proposed.In terms of the power response characteristics of wind farms,a dynamic implementation for section margin calculation was suggested.According to the dynamic calculation results of section margin and the generation state of wind farms,the operation modes of wind farms were dynamically adjusted to realize the self-adaptation between cluster wind power and operation section.A case study based on the actual data of a regional power grid proves that the as-proposed method can reduce wind abundance by about 21.4%,and reduce the section off-limit-time by 33.3%at the same time.The as-proposed method can improve the utilization rate and reduce the out-of-limit time of operation section.
