A method and an apparatus for controlling a Low Voltage Ride Through of a photovoltaic grid-connected inverter. The method for controlling comprises: judging whether a voltage value of a grid is smaller than an upper limit of a low voltage value and is not greater than a lower limit of the low voltage value; when it is judged that a root mean square value of the voltage in the grid is smaller than the upper limit of the low voltage value and greater than the lower limit of the low voltage value, controlling an active current value outputted from the inverter to be equal to a target active current value and controlling a reactive current value outputted to be equal to a target reactive current value, so that a comparison difference between a total current outputted by the inverter in a Low Voltage Ride Through state and a current outputted by the inverter in a normal state is smaller than a preset value. The method and apparatus settle problem that the poor stability is caused since control on the waveform and amplitude of the current is ignored in the Low Voltage Ride Through control on the inverter, such that the total current changes slightly before and after a voltage dip, which can support and stabilize the grid.
