摘要
Abstract
With the continuous expansion of the scale of photovoltaic power generation,the impact of its grid-connected operation on the stability of the power grid is becoming increasingly obvious.A large-scale photovoltaic power generation system model is established,and the PSCAD/EMTDC simulation platform is adopted for experimental analysis to study the influences of factors such as photovoltaic power generation permeability,light intensity fluctuation,and reactive power compensation on the voltage stability and frequency stability of the power grid.Studies show that when the photovoltaic penetration rate exceeds 30%,the transient stability of the system decreases significantly.By configuring reasonable reactive power compensation devices and improving the control strategy of grid-connected inverters,the dynamic characteristics of the system can be effectively enhanced,providing a reference for the grid-connected operation of large-scale photovoltaic power generation.关键词
