摘要:
針對光伏並網後系統小幹擾穩定性的變化情況,基于MATLAB-PSAT仿真軟件搭建了IEEE5機14節點光伏接入系統,詳細研究了不同光伏滲透功率水平下光伏接入對系統振蕩模式阻尼特性的影響。仿真結果表明:光伏的加入不會新增主導的振蕩模式;降低網內機組出力而增加的風電滲透功率時,光伏滲透功率對振蕩模式阻尼比的增幅不大;光伏接入位置對系統整體阻尼特性的影響與發電機有關。
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.
