The rapid growth of load and the access of new energy have made the distribution network face increasing pressure.Distributed energy storage

as an effective means of regulation

can solve such multiple problems as peak-to-valley difference

voltage out of limit and network loss of distribution network

but it needs reasonable control.In this paper

a kind of aggregation control method for distributed energy storage is proposed:Fully distributed control algorithm is used to manage and control multiple energy storage.The method does not need to force the mutual communication and the feedback information of each storage energy output

and the influence of the SOC of each energy storage on the charging and discharging power is considered so that each storage energy can maintain the relative balance of the SOC during the charging and discharging process.And the effectiveness of the method is verified by the simulation result.
