The proposed project present modelling and control of a two-stage grid-tied inverter for integration of different energy sources to the utility grid. The focus of this work is to develop two-level controllers on the AC side so that it can work in both grid-connected mode and standalone mode. The control strategy utilizes the d-q rotation frame and a droop controller to regulate the voltage and frequency of the micro grid. Then the system-level droop controllers are developed to achieve the power sharing among converters in the micro grid. The multiport inverter can interface with multiple renewable energy sources, such as solar panels and wind turbines, and is capable of managing the power flow between the micro grid and the utility grid. Simulation results show that the proposed control strategy is effective in maintaining stable voltage with the load side while also ensuring optimal power sharing among the different renewable energy sources.
