Abstract:
One option to reduce the cost of energy consumption in household sector is the appropriate energy management. This thesis proposes the prototype development and performance testing of Home Energy Management System (HEMS). The design concept and development of the proposed HEMS incorporate three main functions which are smart planning, automatic controlling and energy consumption visualizing. Using Zigbee in transferring data and commands makes some devices inside HEMS communicate with no need of wired cables. In turn, the system can be installed and reused in other places, conveniently. This developed system has been tested at the Power System Research Laboratory (PSRL), Faculty of Engineering, Chulalongkorn University. Test results have shown that the most effective feature in reducing the energy consumption in this case is automatic controlling function, while smart planning and energy consumption visualizing also enhance the potential savings through HEMS. Additional, peak demand control function and web-based graphic user interface development can enhance performance of the proposed system in the future.
