    Abstract By improving the current decoupled control method to reduce the influence of dynamic characteristics of power grid on photovoltaic power system，the DC ?鄄 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.
