| description | The invention relates to the technical field of AC power distribution network operation control, and particularly provides a photovoltaic string control method and device for improving distributed power consumption, and the method comprises the steps: analyzing the three-phase reference electric energy quality of a photovoltaic string based on a power reference instruction transmitted by a distributed photovoltaic cluster; independently carrying out operation monitoring on the three-phase reference electric energy quality of the photovoltaic string to obtain a monitoring result; and determining a voltage reference instruction of the distributed photovoltaic string based on the monitoring result, and controlling on-off of a power device in the distributed photovoltaic string based on the voltage reference instruction of the distributed photovoltaic string. According to the technical scheme provided by the invention, the adjustment of the output power of the string is finer, and the depth adjustment of the dist |
