The invention provides a distributed energy storage scheduling method and a device. The method comprises the following steps: acquiring scheduling parameters; and solving a distributed energy storagescheduling model constructed in advance, and obtaining a distributed energy storage scheduling strategy, wherein the distributed energy storage scheduling model includes operating cost of a thermal power generating unit and extra commuting time cost, and the scheduling parameters include transportation network parameters, transportation demand parameters, electrical equipment parameters and powergrid parameters. The method provided by the invention builds a linear distributed energy storage scheduling model, which can be easily and fast solved, by introducing a conversion coefficient betweena transportation tide and a charging load, and solving is performed by calling a solver, so that solving accuracy of the distributed energy storage scheduling model is guaranteed; and the method provided by the invention considers coupling influence of a transportation tide distribution way and a distributed energy storage scheduling way, impact of the charging load on an electric power system isdampened by virtue of transfer of the transportation tide in space, the total operating cost of the electric power system and the transportation network is reduced, acceptance capability of the charging load is improved, and a theoretical foundation is provided for large-scale connection of the charging load.
