Grid Tie Inverter in a Distributed Generation System with Reactive Power Capabilities

This thesis presents a single phase grid tie inverter with reactive power controller for renewable energy applications in a distributed generation system (DGS). This allows the local renewable energy sources in the DGS to provide the necessary reactive power support to the grid. The inverter utilizes a control algorithm to provide reactive power support to improve the voltage profile of the grid. A traditional grid tie inverter becomes a dynamic reactive power compensator, by regulating the output voltage of the inverter. The reactive support for the grid was implemented by sensing the inverter output voltage to generate its direct and quadrature component in order to generate a reference current signal for a current control loop and thereby controlling the inverter. The system was modeled with Simulink to verify the functionality of the reactive power control in a DGS.
