چکیده
The stability of a grid-tied inverter system will be compromised in weak grid conditions. In order to address this problem, researchers have proposed using power electronics transformer (PET) connect inverters and the grid. By adjusting controller parameters or control strategy, output impedance PET low voltage (LV) converter can varied improve stability. This paper establishes models PET-based evaluates generalized Nyquist criterion. impact variety on is then analyzed. To system, two stabilized strategies, namely virtual digital filter-based methods are proposed. Finally, effectiveness these strategies evaluated through simulations experiments.
