Voltage regulation method and device, electronic equipment and storage medium

The invention provides a voltage regulation method and electronic equipment. According to the specific implementation scheme, under the condition that the grid-connected point voltage of the photovoltaic system is within a preset voltage range, on the basis of the grid-connected point voltage and the grid-connected point current of the photovoltaic system at the first time and the grid-connected point voltage and the grid-connected point current of the photovoltaic system at the second time, a Thevenin equivalent parameter is calculated; calculating a first output power upper limit value of the photovoltaic system corresponding to the voltage lower limit value in the voltage range and a second output power upper limit value of the photovoltaic system corresponding to the voltage upper limit value in the voltage range based on the Thevenin equivalent parameter; determining a first power output function of the photovoltaic system based on the first output power upper limit value and the second output power uppe
