The PFD file "BESS with PWM-Converter 2" contains the BESS with PLL. The PLL makes the model more robust in case of very deep voltage sags. The PWM converter (ElmVscmono) uses directly the voltage angle (real and imaginary part) if no PLL is connected. This can lead to convergence problems in case of very low voltage events.
