A Distributed Energy Storage Capacity Configuration Method Aiming at Reducing Transformer Capacity Expansion

Abstract

The present application discloses a distributed energy storage capacity configuration method, device, equipment, and computer-readable storage medium aiming at reducing transformer capacity expansion. The method includes: determining the total set of energy storage nodes to be installed and the energy storage capacity Total demand; determine the energy storage capacity group to be selected corresponding to each subset; use the pre-established capacity coordination planning model with the goal of minimizing the net cost of energy storage capacity configuration and transformer coordination planning, and optimize the daily operation efficiency of energy storage as The target economic dispatch strategy model processes the candidate energy storage capacity groups corresponding to each sub-set, determines the target candidate energy storage capacity group corresponding to the minimum net cost, and takes the target candidate energy storage capacity group corresponding to the target sub-set as the target sub-set set; get the expansion capacity of the transformer according to the target energy storage capacity group to be selected and the target subset. The technical solution disclosed in the application can reduce the capacity expansion of the transformer, reduce the cost of transformer overload treatment, and improve the utilization rate of equipment equipped for transformer overload treatment.

Description

technical field

[0001] The present application relates to the technical field of transformer processing, and more specifically, relates to a distributed energy storage capacity configuration method, device, equipment and computer-readable storage medium aiming at reducing transformer capacity expansion. Background technique

[0002] With the depletion of fossil energy, environmental problems have become increasingly prominent. Distributed power has been developed rapidly due to its non-polluting advantages. At the same time, EV (Electric Vehicles, electric vehicles) can greatly reduce the use of fossil energy.

[0003] The large-scale EV charging behavior or a substantial increase in other power consumption behaviors have greatly increased the peak load. Because the distribution network did not consider the large-scale EV charging demand or other large-scale increase in power consumption behavior before planning, therefore, the configuration The capacity of the transformer ...
