Abstract: Based on the standard of IEC61850, which used to be applied in the field of intelligent substation for intelligent distribution network, this paper is to analyze the method of Battery Energy Storage Station (BESS) fast accessing smart distribution network. The object-oriented modeling concept of IEC61850 is transplanted into the field of smart distribution power grid to research on BESS ‘plug-and-play’ self-describing, so that the system model can be uploaded to the distribution network control center. Thus saving the effort of checking point tables during the debugging of BESS interconnection with the grid, and realize the quick plug-in of BESS.
