Abstract

The invention provides an energy storage system and a management method. The energy storage system comprises an energy storage converter, a battery manager and a battery pack; the battery pack comprises at least two groups of battery clusters, wherein the energy storage converter is used for executing charging and discharging current transmitted by the battery manager, the battery manager is used for acquiring the current current of each group of battery clusters, determining the charging and discharging current allowed by the battery pack according to the current current of each group of battery clusters and the limiting current corresponding to each group of battery clusters, and transmitting the acquired charging and discharging current allowed by the battery pack in the next period to the energy storage converter, so that the current flowing through each group of battery clusters in the next period is less than the corresponding limiting current. And the charging and discharging current allowed by the battery pack is obtained through repeated iteration until the current flowing through each group of battery clusters in the next period is less than the corresponding limiting current, and the overcurrent condition is avoided, so the safety of the energy storage system is guaranteed.

Description

technical field [0001] The present application relates to the field of power systems, in particular, to an energy storage system and a management method. Background technique [0002] With the development of society and the progress of science, energy plays an important role in people's life. As the energy most closely related to people's life, electric energy is widely used in all walks of life and fields. The supply capacity of electric energy is closely related to people's life. [0003] Due to living habits and working hours, the current power supply network has peaks and troughs in power consumption. In order to supplement the remaining electric energy during the valley of electricity consumption to the power supply network during the peak of electricity consumption, the electric energy storage system came into being. It can be understood that the power energy storage system is used to store the remaining electric energy during the valley of electricity consumption, ...
