The invention relates to the technical field of distributed energy storage, and relates to a distributed energy storage-containing power system optimization operation method, system and device, and the method comprises the steps: 1, obtaining the initial parameters of a system; step 2, establishing a power distribution network optimization operation model containing distributed energy storage; determining constraint conditions of each part of system operation by taking the minimum one-day operation cost of the power distribution network as an optimization target, and solving the established day-ahead economic dispatching model of the power distribution network by using a mixed integer programming method and a second-order cone linear programming method; step 3, calling a Gurobi solver to carry out optimization solution on the model; and 4, by changing the position where the energy storage device is connected to the power distribution network system or the charging and discharging power parameters of the energ
