About Photovoltaic inverter current reverse penetration
The system stability and reliability depend upon the position of DG interconnection. Inappropriate selection of location and DG size will lead to a reduction in voltage stability and an increase in network losses. In this paper, the stability of the system is calculated using the voltage stability index (VSI). The VSI for a two bus.
In this section, the effect of reverse power flow on the protection coordination scheme is analysed. RPF can be due to surplus production at the DG plant, failures produced in the system.
The setting of a protective device depends upon the fault current level. Hence, change in fault current level affects the coordination of protective.

6 FAQs about [Photovoltaic inverter current reverse penetration]
Does high PV penetration affect reverse power flow and overvoltage?
Conclusion Using data from an 11 kV distribution feeder in South Australia, this study has demonstrated that reverse power flow (RPF) and consequent overvoltage are the most critical impacts of high PV penetration.
What is penetration level of PV inverters?
Penetration level of PV inverters is defined as the rating of the network service provider MV/LV distribution transformer supplying the LV distribution as given in (2): (2) P l e v e l ( %) = n p v i s × n d i s t × S i n v S t x × 100 %
How to provide voltage support in PV inverter?
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.
Is a PV inverter a constant power source?
The PV inverter is modelled as a constant power source, however, for fault analysis, the authors assumed the limiting current to be twice the rated current, for the worst-case scenario. The inverter current and voltage are considered in phase for unit power factor operation.
How to reduce voltage rise under high PV penetration?
The developed technique relies on the reduction of reverse power flow throughout the lightly loaded system by enabling the charging controller of energy storage systems. The control strategy is proposed for voltage rise mitigation under high PV penetration while energy storage system is closed to each PV.
What is over current protection mechanism in PV inverter?
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. The triggering of over current protection will lead to disconnection of inverter from the grid which is unfavourable during LVRT period.
