Distributed energy storage capacity configuration method aiming at reducing transformer capacity expansion

Abstract

The invention discloses a distributed energy storage capacity configuration method, device and equipment aiming at reducing transformer capacity expansion and a computer readable storage medium. The method comprises the steps of determining a total set of to-be-selected installation nodes for energy storage and a total energy storage capacity demand; determining a to-be-selected energy storage capacity group corresponding to each subset; processing the to-be-selected energy storage capacity group corresponding to each subset by using a pre-established capacity coordination planning model taking minimum net cost of energy storage capacity configuration and transformer coordination planning as a target and an economic dispatching strategy model taking optimal energy storage daily operation benefit as a target; determining a target to-be-selected energy storage capacity group corresponding to the minimum net cost, and taking a subset corresponding to the target to-be-selected energy storage capacity group as a target subset; and obtaining the capacity expansion capacity of the transformer according to the target to-be-selected energy storage capacity group and the target subset. According to the technical scheme, capacity expansion of the transformer can be reduced, the overload processing cost of the transformer is reduced, and the utilization rate of equipment matched with overload processing of the transformer is increased.

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 ...

Problems solved by technology

[0004] Aiming at the problem of transformer overload, the current commonly used measures are to increase the capacity of distribution equipment (that is, to expand the distribution transformer) or completely use distributed energy storage to meet the needs of transformers when the overload is the most serious, so as to solve the problem of transformer overload. , however, relying only on capacity expansion or distributed energy storage to meet transformer overload will not only have the problem of relatively high investment costs, but also have the problem of low utilization of new equipment
