Abstract: This document presents a Proportional + Resonant (PR) controller design for regulating the active and reactive power output of a three-phase AC Micro-Grid inverter system. The system employs a Voltage Sourced Inverter (VSI). The VSI is configured to operate as a current source through an interface L-filter. The power is controlled indirectly by controlling the inverter’s output current. The stationary reference frame strategy is adopted for the design of the PR controller. A model of a grid connected AC inverter and a detailed design of the inverter’s PR based control scheme are presented. The control scheme is developed and simulated in MATLAB/Simulink software environment. The control algorithm code is generated for a target device. Using Processor In-the Loop (PIL) simulation, functional equivalence testing is performed between the simulated control algorithm and the compiled algorithm code on the target device. Results in both normal and PIL simulations are discussed from the viewpoint of steady state and dynamic performance of the controller.
