Implementation of AMI in City energy management systems

AMI (Advanced Metering Infrastructure) system is constructed for the development of energy management system in this paper. To show a various type of energy saving simulation execution result, renewable systems such as wind, PV, and thermal systems operating site have been selected and the monitoring system of AMI system is built for the measured data. First, the energy demand profile of the reference site is analyzed to calculate reductions after applied the use of renewable sources. Then the operating scenario is determined through RTP (Real Time Pricing). Finally, the outcome of Load Shifting operation is simulated. The result shows that electricity cost can be reduced about 11,600 KRW/day and it is equivalent to 9.65 USD/day, 3.8% saving of electricity cost.
