The invention discloses a distributed energy storage and voltage regulation control method for a power distribution network in a resource aggregator mode, solves the problem of voltage out-of-limit of the power distribution network, and belongs to the field of user-side distributed energy storage. The method comprises the following steps: based on basic data of a power distribution network system, performing equivalent aggregation on user-side stored energy in a resource aggregator mode to form equivalent flexible distributed stored energy scheduled by a resource aggregator, and performing cluster division on the power distribution network; according to different clusters, setting a voltage regulation proportion as an initial value; selecting the most serious node in the cluster with the most serious voltage out-of-limit as a priority adjustment object, calculating a voltage adjustment upper limit and a voltage adjustment lower limit corresponding to an adjustment proportion, performing voltage adjustment by
