Weather data-driven power distribution network adaptive droop voltage regulation method

The invention discloses a weather data-driven power distribution network adaptive droop voltage regulation method, which comprises the following steps of: 1) determining all photovoltaic inverters related to a power distribution network, and acquiring voltage data and power data of all the photovoltaic inverters in the power distribution network according to a set frequency; 2) calculating active power and reactive power of each photovoltaic inverter under coordination control by considering power change characteristics of droop control of the photovoltaic inverter when the radiation intensity changes; and 3) dynamically adjusting photovoltaic power output of each photovoltaic inverter by taking the calculated active power and reactive power as adjustment targets, namely realizing adaptive droop voltage adjustment of the power distribution network. According to the invention, the photovoltaic radiation levels under different weather data are considered, the distributed coordination technology under the constr
