Impact of Reverse Power Flow on Distributed

The reverse power flow phenomenon occurs when the PV power generation in a grid-connected network exceeds the local load demand [17]. This is an indication that RPF is more likely to occur in network regions with lower peak loads.

6 FAQs about [Solar photovoltaic power generation is connected in reverse]

What happens if you reverse power flow in a low-voltage network?

Reverse power flow in a low-voltage (LV) network can cause instability, such as in the line sections and distribution transformers [19, 20]. The overloading of the distribution transformer is one consequence of a low-load, high-PV penetration network; higher voltages are also seen at low-voltage (LV) and medium-voltage (MV) levels. [21, 22].

What happens if solar PV penetration increases?

Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics 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.

Does PV generation cause overvoltage problems?

Nevertheless, at high penetration – when PV generation exceeds the local electricity demand and causes reverse power flow – it can also cause overvoltage problems. Overvoltage problems generally occur at peak PV generation when there is little or no load in the LV network (Aziz and Ketjoy, 2017, Povlsen, 2002).

Why is reverse power flow a problem?

When the volume of distributed generation (DG), including photovoltaic (PV) power systems, is increased, reverse power flow from DG may cause problems. To reduce the reverse power flow from PV power The interconnection of distributed generators (DG) to existing network may give rise to many technical problems.

Why do low-voltage distribution systems need solar photovoltaic (PV) penetration?

Modern low-voltage distribution systems necessitate solar photovoltaic (PV) penetration. One of the primary concerns with this grid-connected PV system is overloading due to reverse power flow, which degrades the life of distribution transformers.

Can reverse power relay operate against bi-directional power flow?

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.
