Smart Metering in electric power distribution system

Electric Energy is a vital resource in everyday life and a backbone to the industry. Being limited its proper use and measurement is very important. Restructuring of power system, penetration of distributed generation and power theft are going to be the key challenges in the near future. The operational information will be crucial for the functioning of the power distribution networks. One of the information sources is going to be the Advanced Metering Infrastructure (AMI). Smart meter is an advanced energy meter that measures electrical energy consumption and provides additional information as compared to a conventional energy meter. It aims to improve the reliability, quality and security of supply. Integration of AMI into electricity grid needs implementation of a variety of techniques, controls and software, depending on the required features. This paper discusses the need of smart meters, their working, benefits and challenges in implementing them. The paper also presents few case studies and cost benefit analysis done earlier.
