Optimized energy consumption management for residential applications controlled by a Local Energy Management Unit

Distribution Grid is evolving into the Smart Grid and users are playing a key role more and more. An efficient network is the aim and Energy Management Systems are being utilized in residential areas in order to contribute to reach this final mentioned goal. The Local Energy Management Unit is presented in this paper, which allows an optimized constant power demand to the Grid, demanding sinusoidal currents to the Grid which are in phase with the Grid voltage. Communications by using TCP and X10 protocols are used to control the whole system and a prototype, which is presented in this paper together with the obtained experimental results, is built to demonstrate the presented efficient energy management conclusions.
