A voltage-source inverter for microgrid applications with an inner current control loop and an outer voltage control loop [PDF]

, 2009
Distributed generation (DG) units are commonly inter-faced to the grid by using voltage-source inverters (VSI’s). Extension of the control of these inverters allows to improve the power quality if the main power grid is disturbed or disconnected. In this
