Development of smart controller with demand response for AMI connection

In order to comprise energy efficiency for electrical devices in homes, a smart grid-base AMI (Advanced Metering Infrastructure), which checks electricity consumption and controls the electric energy used with the demand response technique, is necessary for remotely managing the load of the energy and power consumed. The smart controller calculates the amount of electricity consumed by customer on real time basis from the utility supplier like electric supply company. In this paper, we propose the hardware architecture and software of the smart controller for use as the platform in smart grid system. The smart controller is installed on the electric plug of the electric appliance. The smart controller grasps the electricity amount used in the electric appliance and delivers to the AMI / EMS (Energy Management Server). In addition, according to the electricity price change, the use of energy of the electric appliance is limited. It will also show that it is available to apply to home for efficiently controlling the electric energy consumption.
