PROJECT TITLE :

Bifurcation Analysis of Parallel-Connected Voltage-Source Inverters with Constant Power Loads - 2017

ABSTRACT:

This paper focuses on the stability analysis of a small ac microgrid with two inductive droop inverters driving many identical 3-phase controlled rectifiers, that are modeled as time-invariant nonlinear dynamical constant power masses. A reduced model is adopted for this microgrid, which solely considers the inverter output characteristics, the rectifier input properties, and therefore the transmission line dynamics. Based mostly on this reduced model, the microgrid stability is analyzed for various values of load power using a bifurcation analysis approach.
