Abstract

This paper focuses on the stability analysis of a small ac microgrid with two inductive droop inverters driving several identical three-phase controlled rectifiers, which are modeled as time-invariant nonlinear dynamical constant power loads. A reduced model is adopted for this microgrid, which only considers the inverter output characteristics, the rectifier input properties, and the transmission line dynamics. Based on this reduced model, the microgrid stability is analyzed for different values of load power using a bifurcation analysis approach.
