Summary:Due to the constraints of ecological and environmental protection policies and the continuous improvement of the application scope of clean energy, conventional power supply is gradually replaced. This will result in the hollowing of the conventional power supply, that will become a common phenomenon in receiving-end power grid. And this phenomenon will greatly reduce the support capabilities of the receiving-end power grid and significantly increase the risk of system operation. This paper firstly analyzes the influence of the hollowing of conventional power supply on the frequency and voltage stability of the grid from the mechanism level. And then four different scenes of the hollowing of conventional power supply were further established and the availability of the impact mechanism was verified by the calculations.
