The goal of this project is to propose a dynamic power decoupling (DPD) procedure for the three-stage PV control framework under the uneven network blame situation. A two phase structure comprises of an interleaved dc-dc converter and a three-stage dc-air conditioning inverter is used for the PV control framework. Under ordinary activity, the framework will track the most extreme PV control and also exchange the vitality to the lattice. In any case, if an unbalanced grid blame happens, there will be a twofold line frequency wavering on the yield control.
Accordingly, the twofold line frequency ripple will happen on the dc-interface voltage. The most straightforward approach to manage this issue is to expand the dc-interface capacitance, yet the cost and size of the circuit will be expanded while the unwavering quality of the framework will be diminished. In this manner, the point of this paper is to propose a DPD technique for the three-stage PV control framework to stifle the dc-interface swaying caused by the unequal matrix blame without expanding the dc-connect capacitance. Operational standards and intensive numerical inductions will be exhibited in this project. At last, both reenactment results and equipment confirmations acquired from a model circuit exhibit the execution and plausibility of the proposed procedure.
