The impact of BESS on power system stability

Hello everyone, I am researching the impact of BESS on power system stability. In the simulation, a three-phase short-circuit fault occurs at the 50% position of the transmission line for 0.1s before being cleared. During the fault, the frequency and voltage response are quite irregular compared to the case without BESS. Below are the dynamic parameters of the BESS I used. Where is this parameter set incorrect? P/s: I can't upload directly file to here, so this is link folder contain .dyr and .out file. Thank you
