Abstract

With the increasing capacity of PV systems in the grid, the grid-connected PV systems will have negative impacts on the grid in the case of a disturbance or a fault. In this study, a strategy of ‘DC voltage control’ is adopted. During the period of low voltage ride through (LVRT), the duty cycle of the boost circuit is adjusted to reduce the output power of the PV battery so that the DC side voltage will be limited. Also reactive power is provided according to the depth of grid voltage sags to support voltage recovery of the grid. Consequently LVRT is realized successfully. Finally, the control strategy is verified in MATLAB/SIMULINK.
