Research on grid-connected interoperability technology of battery storage power station

In the context of the large-scale application of energy storage, the PCS and BMS systems of the battery energy storage system need to be connected to the communication network, the communication interaction efficiency is low, and the process is complicated. In order to solve this problem, this paper researches the information exchange mechanism of grid connection to the common problems existing in the information flow level of battery storage power stations connected to the regional power grid. Through the analysis of the function of the battery storage power station, the self-discovery technology and the interoperability technology of the information interface device are mainly studied to solve the technical problem of the plug-and-play information level of the battery storage power station. As a result, the battery storage power station can directly jump from restricted access to orderly access, and the adaptability of battery storage power stations in different application scenarios can be improved.
