Control and Performance Analysis of a Single-Stage Utility- Scale Grid-Connected PV System

For utility-scale photovoltaic (PV) frameworks, the control goals, for example, greatest power point following, synchronization with grid, current control, and harmonic reduction in yield current, are acknowledged in single stage for high efficiency and simple power converter geography. This paper considers a high-power three-phase single-stage PV framework, which is associated with a dissemination organization, with an adjusted control procedure, which incorporates pay for grid voltage plunge and reactive power
infusion capacity. To manage the dc-interface voltage, a changed voltage controller utilizing criticism linearization plot with feed-forward PV current sign is introduced. The genuine and reactive powers are controlled by utilizing dq segments of the grid current. A little sign steadiness /eigenvalue investigation of a grid-associated PV framework with the total linearized model is performed to evaluate the power of the controller and the decoupling character of the grid-associated PV framework. The powerful presentation is
assessed on a constant advanced test system.
