Abstract

A novel droop controller is developed employing parallel voltage and current control algorithms. P-F droop is performed by a voltage controller in the direct axis of the rotating reference frame, whilst Q-V droop is achieved via a deadbeat current controller in the quadrature axis. Simulation and hardware results are presented to demonstrate the control schemes ability to provide matched and mismatched power sharing utilising a low voltage two inverter microgrid.
