But for an inverter to provide that much power, it has to draw the same amount of power from the battery. Battery is lower voltage, so higher current. So about 100A continuous current would be drawn from the battery, if inverter was 100% efficient. assume inverter is 80% efficient. 100A/0.80 = 125A, so that is the continuous current.
If is between 0.9 and 1.1 p.u., the controller operates normally (Normal). If is between 0.5 and 0.9 p.u., the inverter is required to inject both active and reactive power to the grid simultaneously (Sag I). Finally, when is smaller than 0.5 p.u., the inverter should inject only reactive current to the grid (Sag II).
The results under two-phase and three-phase dip in the grid voltage shows that the proposed control strategy injects maximum reactive and active power and limits the inverter current by quickly activating the APC control loop during fault-ride-through period.
So about 100A continuous current would be drawn from the battery, if inverter was 100% efficient. assume inverter is 80% efficient. 100A/0.80 = 125A, so that is the continuous current. Do you have any loads with a motor? Starting a motor requires additional current. You may notice that lights dim momentarily when it turns on.
To provide overcurrent limitation as well as to ensure maximum exploitation of the inverter capacity the performance of the proposed control strategy, is evaluated as per the three generation scenarios given below: In this case, the inverter’s capacity is majorly exploited through the injection of active power under normal operating condition.
To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.
