An Adaptive Droop DC-Bus Voltage Controller for a Grid-Connected Voltage Source Inverter with LCL Filter - 2015 PROJECT TITLE: An Adaptive Droop DC-Bus Voltage Controller for a Grid-Connected Voltage Source Inverter with LCL Filter - 2015 ABSTRACT: This paper presents a very quick dc-bus voltage controller for one-phase grid-connected voltage-supply inverter (VSI) with an LCL output filter utilized in renewable energy applications. In single-part grid-connected inverters, the design of the dc-bus voltage control theme is very difficult thanks to the presence of a second harmonic ripple across the dc-bus voltage. The proposed dc-bus voltage control theme is in a position to handle the difficulties introduced by the second-harmonic ripple. The dc-bus voltage controller is predicated on an adaptive droop control technique, which is in a position to supply a terribly quick transient response for the closed-loop system and ensures the optimal operation of the VSI during steady-state conditions. Additionally, the simple structure of the controller makes it very sensible for grid-connected VSIs employed in renewable energy power conditioning systems. Theoretical analysis and experimental results demonstrate the superior performance of the proposed control approach compared to standard dc-bus voltage management schemes.
