The rising issue of voltage regulation in distributed generation (DG) is being addressed through centralised voltage control (also known as active network management). Intelligent distributed voltage and reactive power regulation of DG has also been developed with positive results, allowing for the connecting of bigger generators to the distribution network with less voltage fluctuation and fewer voltage violations. Network operations will be tested when consumers give way to prosumers, who generate energy, particularly at the low voltage distribution level. To ensure power quality and safe device operation, voltage levels must be kept within permitted limits. In networks where renewable energy sources account for a considerable proportion of production, voltage regulation may soon be a necessity. Nearly every node now has access to power quality measuring equipment thanks to the widespread adoption of smart metres and other forms of automated metre reading. The network's voltage and power can be checked for synchronicity with the use of power snap shop analysis. Characteristics of the network and key nodes can be discovered through automated analysis of this massive data set. Using power snapshot data, this work demonstrates automatic evaluation of essential voltage nodes, a requirement for the creation of effectively run low-voltage grids.
