Abstract. The power generated locally exceeds the demand with the increase in solar PV penetration to the distribution grid, and reverse power flow will occur. As solar PV penetration increases, the reverse power flow and the short-circuit current level increase.
In this paper, a protection scheme against reverse power flow concerning PV integrated grid system are being discussed. This paper aims to explore recourses to modify the existing protective schemes and investigate reverse power relay (RPR) operation against bi-directional power flow to accommodate PV-DG in distribution networks.

6 FAQs about [Principle of reverse grid connection of solar power generation]
What are grid-interactive solar PV inverters?
Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.
Do grid connected solar PV inverters increase penetration of solar power?
The different solar PV configurations, international/ national standards and grid codes for grid connected solar PV systems have been highlighted. The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined.
Why is a battery-less grid-linked solar PV system a good choice?
However, a battery-less grid-linked solar PV system is selected for utility power scale level because these systems are implemented in high or medium power size ratings. Because of this, the grid-linked solar PV system with battery storage system is rather large, making the large-scale solar PV grid integrated layout unattractive and unprofitable.
Can grid-connected PV inverters improve utility grid stability?
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
How do PV systems maintain grid connectivity?
Particularly at high PV penetration levels, PV systems should maintain grid connectivity through reactive power injection in reaction to voltage faults to prevent instigating extreme incidents, such as blackouts. To further reduce the cost of energy, it is necessary to enhance both dependability and efficiency.
What is a grid-connected PV system?
Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid. The application of the system will determine the system’s configuration and size. Residential grid-connected PV systems are typically rated at less than 20 kW.
