To exploit the voltage support capability of PVs and EVs, this paper proposes a two-stage control scheme for the voltage regulation of distribution networks, consisting of the day-ahead and intraday control stages.

In addition, the voltage fluctuation and power quality issues may limit the PV penetration level and hence mitigation measures are needed to alleviate the potential problems. In this paper, the impact of PV on the distribution network in term of voltage performance and losses has been investigated by using the OpenDss simulator tool.
Conventionally, the distribution network voltage regulation is in the charge of the local distribution network operator (DNO) and is conducted in a centralized way with the operational settings of OLTC transformers and SCBs globally optimized.
As the penetration level of solar PV rises over the coming decades, reverse power flow on the distribution feeder will happen more frequently and the associated voltage rise might lead to violations of voltage boundaries defined by ANSI C84.1.
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.
In addition, in , to prevent overvoltage problems in power distribution networks, the use of the battery has an important role and three various scenarios for grid conditions, are tested as the voltage control mode, mitigating reverse power flow mode, and scheduling mode.
Current power systems are not designed to support the massive integration of PV and to respond to the grid codes. The application of intelligent and online control methods for better coordination between all parts of modern electrical systems is very important.
