Transgressions in voltage levels, such as VU, are more identified in the LVDN due to the irregular distribution of loads per phase, which varies constantly, and in addition to these factors, energy is injected through single-phase solar generators [8], [9], [11], [12], [14], [32].These anomalies affect the operation and can cause the burning of electronic equipment,
By enabling more efficient and reliable integration of solar PV systems into distribution networks, this approach opens the door for increased adoption of renewable energy sources.

The installation of rooftop solar PV in the LV distribution network may pose potential threats to distribution system operators due to the reversal power flow and reactive power disturbance.
This reactive power can be utilized to minimize tap operation instances of VRs or to resolve voltage quality issues such as voltage imbalance, voltage sag, or voltage fluctuations . However, active power curtailment is in general not recommended because it causes significant energy losses [ 173, 202 ] and is unfair to PV owners [ 180 ].

As a result, the number of solar photovoltaic (PV) systems connected to the low voltage network has shown a rapid increase around the world. Many studies are being carried out to analyze the potential impact of high penetration of solar PV on the operation and performance of electricity distribution systems.
For distribution networks with increasing PV integration, a local voltage regulation approach is suggested in . A very short-term solar generation forecast, a medium intelligent PV inverter, and a reduction of the AP are reported as forecast techniques.
Some major standards for PV integration in distribution systems such as IEC 61727, IEEE 1547, and VDE-AR-N4105 are defined and used in to ensure that the power quality and stability defined by grid codes for PV sources connected to the grid are maintained.
5. Conclusions Due to the intermittent power generation of distributed PV systems and the spatiotemporal uncertainty of uncontrolled EV charging, the accelerating grid penetration of EVs and PVs brings in severe voltage deviations and voltage fluctuations.
The PV systems and EVs act as supplementary voltage regulation resources. The PV systems are always grid-connected, and their voltage regulation capability is achieved using the device-level reactive power control, with the control range mainly determined by the operating power level (and hence the solar irradiation level).
In distributed voltage control, the distribution network with EVs and PVs connected is first partitioned into several regions based on the similarity of bus voltage sensitivity. Then, regional voltage control is applied to each regional distribution network via the active and reactive power control of their member EVs and PVs [34, 35].
