The invention provides a photovoltaic-containing power distribution network distributed energy storage coordination voltage control method. The method comprises the steps of determining a tail end bus-connected and energy storage-participated voltage control power reference value; selecting each distributed energy storage power value based on communication connection; selecting distributed energystorage power values considering state of charge constraints; and carrying out energy storage power correction of communication triggered based on events. According to the voltage level of the corresponding bus, the proportion of the participating voltage control power of the energy storage on each bus is determined, and by being communicated with the adjacent buses, distributed voltage control isrealized. A communication scheme triggered by an event is introduced for data transmission between adjacent battery energy storage systems. The tail end bus-connected and energy storage-participatedvoltage control power is used as a virtual leader value, and the information is transmitted to other buses through communication links between feeder lines and the adjacent buses. Therefore, the voltage of each bus is within an allowable range, the influence of voltage fluctuation caused by photovoltaic access is reduced, and the high-permeability extinction of the distributed photovoltaic is promoted.
