This paper proposes a nonlinear control methodology for three phase grid connected of PV generator. It consists of a PV arrays; a voltage source inverter, a grid filter and an electric grid. The controller objectives are threefold: i) ensuring the Maximum power point tracking (MPPT) in the side of PV panels, ii) guaranteeing a power factor unit in the side of the grid, iii) ensuring the global asymptotic stability of the closed loop system. Based on the nonlinear model of the whole system, the controller is carried out using a Lyapunov approach. It is formally shown, using a theoretical stability analysis and simulation results that the proposed controller meets all the objectives.

For utility-scale photovoltaic (PV) systems, the control objectives, such as maximum power point tracking, synchronization with grid, current control, and harmonic reduction in output current, are realized in single stage for high efficiency and simple power converter topology. This paper considers a highpower three-phase single-stage PV system, which is connected to a distribution network, with a modified control strategy, which includes compensation for grid voltage dip and reactive power injection capability. To regulate the dc-link voltage, a modified voltage controller using feedback linearization scheme with feedforward PV current signal is presented. The real and reactive powers are controlled by using dq components of the grid current. A small-signal stability/eigenvalue analysis of a grid-connected PV system with the complete linearized model is performed to assess the robustness of the controller and the decoupling character of the grid-connected PV system. The dynamic performance is evaluated on a real-time digital simulator.

Abstract. An essential issue of the high-frequency isolated converter interconnecting the AC/DC hybrid microgrid is the magnetic flux bias, which will cause saturation of magnetic core if not controlled appropriately. In order to solve the problem, this paper analyzes the reasons of the flux bias and models the magnetizing current in the s-domain. Based on the analysis and the model, a strategy for magnetic flux bias reduction is proposed. The strategy compares the peak of the magnetizing current at each switching time and controls the average of the magnetizing current to zero by applying an additional voltage to the winding of the transformer at the DC side. The simulation base on PSIM platform is implemented and the results verify the validity of the proposed strategy.
