In this paper, photovoltaic power generation(PV) and the asynchronously grid-connected power grid are taken as the research objects, and the frequency adaptability of PV to power grid is studied. The influence mechanism of grid frequency variation on PV is revealed, and it is proposed that the frequency tolerance range of PV is mainly determined by the setting value of inverter protection and PLL parameters. The whole process simulation of wind turbine adaptability under frequency change is realized on Matlab/Simulink, and the simulation results verify the correctness of the conclusion.
