Abstract

The invention discloses an energy storage system monitoring method, device and system. The energy storage system monitoring method, device and system can determine the current operation state of an energy storage system; according to a pre-established corresponding relation between the operation state of the energy storage system and a to-be-monitored data item, a target to-be-monitored data itemmatched with the current operation state is determined, wherein the to-be-monitored data item is a part or all of the data items in the operation data of the energy storage system; a data monitoring request is sent to a monitoring module for requesting the monitoring module to collect the data of the target to-be-monitored data item; and the data, collected by the monitoring module, of the targetto-be-monitored data item is received. Due to the fact that the monitoring module does not collect all data items in the operation data of the energy storage system at all moments, and only the targetto-be-monitored data item matched with the current operation state of the energy storage system is collected. Therefore, the data volume acquired by the monitoring module can be reduced, so that thecommunication data volume between the energy storage system and an upper layer controller is reduced, and the transmission resources are saved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to an energy storage system monitoring method, device and system. Background technique [0002] The Energy Storage System (ESS) is generally composed of two parts: the energy storage converter and the battery module. The energy storage system can quickly respond to changes in the grid load and adjust the power of the access point. It is widely used in in the power system. [0003] When the energy storage system is applied to the power system, the operating data of the energy storage system will be monitored. During the monitoring, all the operating data of the energy storage converter and the battery module of the energy storage system will be monitored, and all the monitored operating data will be uploaded to the upper controller in the power system in real time. The upper controller can control the operation of the energy storage system according to the receive...
