In addition, overvoltage is much more severe at the solar PV inverter bus compared to that at the POM. This issue was singled out as a key finding and further study to develop a better understanding was recommended by NERC.
Scientists at the University of South Australia have identified strategies to prevent solar power losses when overvoltage-induced inverter disconnections occur due to voltage limit violations.
This mode may be triggered by sudden inverter current ramp down, or momentary cessation, leading to overvoltage most severe at the capacitor bus. In , the shunt compensation is assumed to be connected at the inverter bus. Therefore, the inverter bus shows the most severe overvoltage.
Following that event, in 2018, two more solar PV tripping events occurred in California, also due to sub-cycle overvoltage . The NERC report points out that inverter’s momentary cessation, shunt compensation at the POM bus are interrelated to sub-cycle overvoltage.
Between a solar PV and the substation, there exist collecting lines and step-up transformers to boost the output voltage of a PV plant. If the sub-cycle overvoltage is predominantly caused by the interaction of the shunt capacitor and the grid inductive impedance, overvoltage would be most severe at the substation bus.
Contribution to overvoltage is very limited. Hence, the impact of a filter is ignored. This paper offers a quantitative analysis to explain the role of inverter control in aggravating sub-cycle overvoltage. This paper will set to analyze the frequency responses of inverter controls.
