Why is PV overvoltage a problem?

Several distribution system operators (DSOs) have been experiencing overvoltage issues due to the high level of PV penetration, such as in Italy, Spain, Ireland, and Germany [ 2 ]. Once the peak generation of PV systems coincides with the low local loads, reverse power flow occurs and voltage gradually rises [ 3 ].

Can photovoltaics cause overvoltage in low voltage distribution feeders?

As non-controllable power sources, photovoltaics (PV) can create overvoltage in low voltage (LV) distribution feeders during periods of high generation and low load. This is usually prevented passively by limiting the penetration level of PV to very conservative values, even if the critical periods rarely occur.

Are solar PV inverters a viable solution to overvoltage problems?

Among the different voltage controls provided by solar PV inverters, active power curtailment [ 6, 7, 8, 9, 10] and reactive power management [ 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] have been established as viable solutions for the overvoltage problems associated with extensive solar PV penetration in LV distribution networks.

Does high PV penetration cause overvoltage?

The overvoltage caused by high PV penetration and the solutions for facilitating high share of PV systems were illustrated using the provided mathematical framework, and an evaluation of localised, distributed, and centralised voltage control methods was presented using the voltage sensitivity analysis.

Why is overvoltage a problem in LV grids?

However, overvoltage is the main challenge in many LV grids with PV, and is one of the main limiting factors in increasing PV penetration in LV grids. Overvoltage caused by PV systems happens when the power flow path is reversed from customers to the LV transformers.

How to control overvoltage in a PV generator?

An effective way to correct the unacceptable overvoltage is to control the reactive power of the line through the inverter of the PV generators whenever an out of limit overvoltage is detected.
