【 摘 要 】

As the single-phase rooftop photovoltaics (PVs) are installed into the three-phase low voltage (LV) distribution network, the network voltage profiles become unbalanced. Although the load at the customer side has already imbalanced the network, as the single-phase rooftop PVs with random ratings of 1-5kW are installed, the power quality issues, such as voltage magnitude and angle, frequency, active and reactive powers become significantly noticeable. This is because of the grid infrastructure from plants to beyond the customer side is disrupted as several utility devices added into the network. This paper aims to implement the concept of several internets of things (IoT) techniques into the electric and communication infrastructures as they are virtuously cycling, enabling, amplifying and reinforcing the infrastructure development. This concept also applied to the voltage regulation technique (VRT), in order to improve the voltage unbalanced and other power quality issues. This communication-based VRT has been conducted by the authors in their previous studies. The results show that the concept of IoT techniques successfully implemented if both communication devices and technology properly selected and designed. Additionally, the considered classifying of the communication layers also plays an important role to coordinate sensors actuators and meters along the feeder of the LV network.
