| Abstract |
This paper studies the sensitivity of power dynamics for technically possible variations of operating point and line impedance of a droop controlled voltage source converter (VSC) connected to a stiff low voltage grid. The influence of the control parameters of traditional droop, improved droop and power-synchronizing control are analyzed by also considering their interaction with internal control dynamics and reactive power droop control. Finally, parameter selection rules are proposed that yield a robust behavior in all studied scenarios by quantifying the damping constant and finding it to be always equal to one. |
