Under grid voltage sags, over current protection and exploiting the maximum capacity of the inverter are the two main goals of grid-connected PV inverters. To facilitate low-voltage ride-through (LVRT), it is imperative to ensure that inverter currents are sinusoidal and remain within permissible limits throughout the inverter operation.
To provide over current limitation as well as to ensure maximum exploitation of the inverter capacity, a control strategy is proposed, and performance the strategy is evaluated based on the three generation scenarios on a 2-kW grid connected PV system.
Afrin, N., Yang, F. & Lu, J. Voltage support strategy for PV inverter to enhance dynamic voltage stability of islanded microgrid. Int. J. Electr. Power Energy Syst. 121, 106059 (2020).
When a fault (such as a short circuit, flickering, or loss of grid power) occurs on the grid, even if it is transient in nature, the conventional grid-tied PV inverters automatically cut themselves off from the grid. The inverters are configured in this fashion to prevent damage from transients of over current or over voltage.
Step changes in the inverter’s reference power show the strategy’s quick adaptation to reactive power demands, while maintaining a stable active power supply. Furthermore, active power control disconnects the BESS when it approaches its lower SoC limit in a near-depleted battery scenario.
It can be observed from Fig. 6 d, 8 d and 10 d that under single-phase grid voltage sag, the injected inverter currents remain below the rated inverter capacity and the maximum exploitation of the inverter’s capacity is achieved.
