Problems solved by technology

[0002] A large number of decommissioned power batteries (referred to as decommissioned power batteries) that are idle due to replacement and decommissioning in new energy vehicles can be used as energy storage systems in microgrids after being sorted into groups, providing support for new energy consumption and power grid peak shaving and valley filling , but due to the limited capacity of a single decommissioned power battery pack, multiple decommissioned power battery packs need to be used in combination when used in large-capacity occasions, which increases the dispatch scale of decommissioned power batteries, and the existing sorting method sorting The performance consistency of the decommissioned power battery packs is not high, which not only increases the complexity of decommissioned power battery scheduling, but also makes it difficult to accurately manage single batteries, resulting in low utilization of decommissioned power batteries
In addition, even after sorting, the performance difference of retired power battery packs is much greater than that of new power battery packs. If they are directly dispatched in a centralized manner without considering the performance differences of each battery pack, some battery packs will Insufficient use and overuse of some battery packs lead to a reduction in the economy of all battery packs, and differences in the performance of single cells in decommissioned power battery packs still exist. low capacity utilization

Embodiment 1

[0045] figure 1 It is a flowchart of a hierarchical grouping cooperative optimization scheduling method for decommissioned power battery groups according to an embodiment of the present invention. Such as figure 1 As shown, the collaborative optimization scheduling method includes the following steps:

[0046] S1. Establish a hierarchical group collaborative scheduling framework for decommissioned power battery groups, wherein the hierarchical group collaborative scheduling framework includes a central control layer, an inter-group collaborative scheduling layer, and an intra-group scheduling layer.

[0047] Specifically, such as figure 2 As shown, the top layer of the group-by-layer cooperative scheduling architecture for decommissioned power battery groups is the central control layer, which is responsible for sorting and dispatching decommissioned power battery groups into groups and issuing dispatching instructions. The dispatching object is each decommissioned power ba...

Abstract

The invention discloses a hierarchical grouping collaborative optimization scheduling method for retired power battery groups. The method comprises the following steps of establishing a hierarchical grouping collaborative scheduling architecture of the retired power battery group; establishing a sorting and grouping system on a central control layer of the architecture so as to group retired powerbattery groups and obtain a plurality of retired power battery packs; obtaining the operating parameters of the microgrid and making the scheduling plans of the retired power battery packs accordingto the operating parameters of the microgrid and performance differences among the retired power battery packs; executing an upper-layer scheduling plan between inter-group cooperative scheduling layers so as to complete power scheduling among the retired power battery packs and formulate an intra-group scheduling plan of each retired power battery pack; and executing anintra-group scheduling planbetween intra-group scheduling layers so as to complete power distribution of each single retired power battery in the group. According to the scheduling method, the scheduling complexity of the retired power battery group can be reduced. The accurate scheduling from the group to the individual is realized, and the utilization rate and the economy of the retired power battery are improved.
