Summary:An active current detection technique (ACDT) for a three-phase grid integrated photovoltaic system is presented in this research. As a result of using the triangle character function for component extraction, the suggested control reduces the overall computing load. This demonstrates the efficacy of the proposed ACDT under a range of operating situations. Control algorithm design also provides desired voltage regulation, decreasing peak overshoot during transient conditions. This will also aid in the rapid and precise regulation of grid current concerning the reference current. Further, the fractional-order controller is adopted for DC-link voltage stabilization during transient dynamics of the system. The suggested control algorithm successfully maintains a constant power flow to meet the load requirement. Finally, simulation experiments were conducted in the Matlab Simulink in order to validate the proposed controller ability. The simulation result shows proposed control performs well subject to system perturbation.
