The invention provides an electric vehicle-participation power grid low voltage control method based on deep learning. The method specifically comprises the following steps: collecting historical low voltage fault data, a corresponding electric vehicle load removal scheme and a voltage recovery effect thereof; calculating a relationship between the electric vehicle load removal scheme and the voltage recovery effect; calculating the influence value of each node load on the voltage recovery effect; establishing a power grid optimization model according to the reliability requirement of power grid voltage recovery, the electric vehicle load removal cost, the influence value of each node load on the voltage recovery effect, and the relationship between the electric vehicle load removal scheme and the voltage recovery effect; and when the method detects that the electric vehicle-participation power grid has low-voltage fault condition, acquiring an electric vehicle load removal scheme corresponding to fault processing according to the corresponding load shedding demand through the power grid optimization model. According to the method, a more accurate electric vehicle load removal scheme can be obtained, the recovery speed of the power grid can be improved, and the power supply reliability of the power grid is improved.
