Primary Frequency Reserve Optimization of New Power System Considering Stochastic-extreme Disturbance
随着弱支撑能力的新能源电源高比例接入,新型电力系统频率稳定问题成为研究热点.该文研究考虑随机-极端扰动的一次调频备用优化问题.首先,以多机系统频率响应模型为分析对象,将扰动建模为高斯白噪声随机扰动和常规有功阶跃扰动之和;其次,为解析刻画调速器在线性和饱和状态对频率动态的影响,将多机系统频率响应模型聚合为分段线性单机等值频率响应模型,构建频率动态的时域随机微分方程(stochastic differential equation,SDE)模型,并分…查看全部>>
With the penetration of the high proportion of renewable energy sources with weak support capacity,the frequency stability of new power systems has become a research hotspot.This paper studies the optimization problem of primary frequency regulation reserve considering random-extreme disturbance.Specifically,the frequency response model of multi-machine system is taken as the analysis object,and the disturbance is modeled as the sum of Gaussian white noise r…查看全部>>
