基于能量函数和改进虚拟同步控制的低频振荡抑制策略OA
Low-frequency oscillation suppression strategy based on the energy function and improved virtual synchronization control
随着可再生能源发电的普及和电力电子设备装机规模的扩大,电网稳定性显著降低,虚拟同步发电机(VSG)技术近年来备受关注.然而,VSG与同步发电机并网受到扰动时,VSG虚拟转子转速会发生突变,从而引起系统输出大幅度波动.为了抑制这些波动,本文提出一种基于超前滞后控制环的附加功率和惯量的VSG控制方法.通过引入能量函数的概念,得到一种新的控制策略.利用能量函数,分析VSG参数对系统低频振荡的影响,并通过调节VSG参数实现对VSG输出能量的控制,减少VS…查看全部>>
The power grid's stability has substantially declined as a result of the growing popularity of renewable energy sources and the scale at which power electronic equipment is being installed. In light of this,virtual synchronous generator (VSG) technology has drawn a lot of attention lately. Nevertheless,the virtual rotor speed of the VSG experiences abrupt variations when the grid connection of synchronous generators is disrupted,leading to notable oscillatio…查看全部>>
