The objective of this paper is to show the characteristics of smart meters enabling to monitor and analyze the low-voltage (LV) network. This is achieved by developing use cases, where power quality and outage data are transferred from smart meters through distribution network to the control center. To visualize the monitoring process of LV network, the use cases are mapped into smart grid architecture model. The paper proposes a solution to analyze the LV network interruption and power quality

The rapid transition of smart meters from traditional meters has provided many benefits to utilities, distribution system operators (DSOs) and customers. The customers can check the hourly consumption data for electricity usage and control their energy usage by receiving tariff information. Smart meters enable DSO to get state estimation, interruption measurement, and asset management. The information regarding interruption measurement can be gathered by deploying smart meters at the customer level and at the substation level, which reduces the time at the control center to identify the affected power supply area. Initially, automatic meter reading (AMR) meters were deployed to read the electricity energy consumption with one-way communication for accurate billing, and for reducing the cost of labor for a meter reading. However, after the invention of advanced metering infrastructure (AMI), the smart meters with two-way communication participated in different operations, such as tamper detection, theft detection, managing peak demand, fault management, power quality monitoring, and network planning. The smart meters are a part of the AMI network that uses different information and communication technology (ICT) solutions to send and receive the data. The collected data can be analyzed and utilized for other purposes (data mining for smart home solution), consisting of consumption data, events and alarms (Wang et al., 2016) .
