摘要

Abstract

Transient angle stability of inverters equipped with the robust droop controller is investigated in this work. At first

the conditions on the control references to guarantee the existence of a feasible post-disturbance operating point are derived. Then

the post-disturbance equilibrium points are found and their stability properties are characterized. Furthermore

the attraction regions of the stable equilibrium points are accurately depicted by calculating the stable and unstable manifolds of the surrounding unstable equilibrium points

which presents an explanation to system transient stability. Finally

the transient control considerations are provided to help the inverter ride-through the disturbance and maintain its stability characteristics. It is shown that the transient angle stability is not a serious problem for droop controlled inverters with proper control settings.
