Smart meters are a two‐way communicator that helps create a bridge between the utilities and the end consumer. In comparison to existing meters, smart meters have included functionalities by using real‐time sensors, power outage notification, and power quality monitoring. Smart meters function digitally and permit automatic and complex transmissions of data between utilities and customers. Sharing information through smart meters can be linked to a Home EMS, which allows the consumers to see it in a comprehensible format which helps them to control their energy usage. To have a safe and reliable grid, various devices and algorithms that allow for rapid diagnosis and analysis should be developed.

AMI includes the implementation of various technologies that allow for a two‐way flow of information, providing consumers and utilities with information on electricity cost and use, including the time and amount of electricity used. AMI gives a wide range of functionalities such as [38]:

1 1) Remote consumer price signals, which can provide time‐of‐use pricing information.

2 2) Collect, store, and report users' energy consumption data for any needed periods.

3 3) Enhance energy diagnostics from detailed load profiles.

4 4) Obtain location and degree of outages remotely.

5 5) Provide the possibility for remote connection and remote disconnection.

6 6) Allow identification of electricity theft and losses.
