Abstract
This study examines how the grid-integrated hybrid system responds to a grid fault caused by a lag in the inverter's closed loop control time. Modeling of the hybrid renewable energy system with solar PV, Doubly Fed Induction Generator incorporated wind power, and the subsequent connection to the AC grid for providing energy to the three-phase load with Closed Loop control scheme of the VSI is presented in detail. This system incorporates solar PV and wind power. An MPPT approach is utilised in conjunction with a DC-DC boost converter in the Solar PV system. The wind power conversion system is combined with VSI's output to produce a hybrid system. The closed-loop controlled VSI's output is evaluated with a delay and while it's running normally. Closed loop control delay has a significant impact on grid output, and an effective real-time control solution for the VSI is therefore required.
