Key ICT solutions for realizing smart grid

Smart Grid is receiving plenty of attention as the next generation energy management system which allows both bulk renewable energy installation and optimized energy production and consumption. In order to realize Smart Grid, it is said that ICT, Information Communication Technology, takes important roles, and we acknowledge following two ICT solutions are especially significant. The first is Advanced Metering Infrastructure (AMI) which is the last mile network solution connecting energy suppliers with their consumers, and the second is the Energy Management System (EMS), which provides various measures for optimized energy supply and demand. Both solutions are based on new requirements in electric power market and many challenges exist in deployment of these solutions. In this paper, technologies and ideas which solve these challenges in both AMI and EMS areas are provided to realize Smart Grid based on our implementation and development experiences of these solutions.
