改进的光伏发电系统并网控制技术

摘要

对传统光伏发电系统直流侧电压控制进行改进，采用改进电流解耦控制方法，减少电网动态特性对光伏发电系统的影响。在Matlab／Simulink中进行仿真．结果显示这种控制方法可有效提高控制效果。%By improving the current decoupled control method to reduce the influence of dynamic characteristics of power grid on photovohaic power system, the DC-link voltage control technology of traditional photovoltaic power system is improved. From the simulation in Matlab / Simulink, it is shown that this control method improves the control effects effectively.
