摘要:
针对光伏并网后系统小干扰稳定性的变化情况,基于MATLAB-PSAT仿真软件搭建了IEEE5机14节点光伏接入系统,详细研究了不同光伏渗透功率水平下光伏接入对系统振荡模式阻尼特性的影响。仿真结果表明:光伏的加入不会新增主导的振荡模式;降低网内机组出力而增加的风电渗透功率时,光伏渗透功率对振荡模式阻尼比的增幅不大;光伏接入位置对系统整体阻尼特性的影响与发电机有关。
Abstract:
In allusion to the variation of small disturbance stability of power grid after grid-connection of solar photovoltaic generation in this paper, the 14 nodes photovoltaic access system of IEEE5 based on the MATLAB-PSAT simulation software is built, and the influence of photovoltaic access on the damping characteristics of system oscillation mode is studied in detail. The simulation results show that the new model will not join PV oscillations driven by reduced output; When the wind power penetration decreases with the increase of wind turbine power output, the increase of the PV power of the damping ratio is not significant; the influence of photovoltaic location on the overall system damping characteristics associated with motor.
