Smart home demonstration on LabVolt Home Energy Production Training System

Singapore looks forwards to become a smart nation. Working towards smart nation and smart grid, smart homes are the fundamental building units of power distribution system. Smart home can have photovoltaic system and storage system together with electrical vehicles. This paper presents modeling and simulation of smart home energy management system on LabVolt Home Energy Production Training System. A smart home system is implemented by a photovoltaic (PV) module, battery storage modules, DC/AC converters and load modules. The objective of the home energy management system is to supply electricity to the loads while maintaining comfort level of the residents. The created system provides a platform for simulating and analyzing real-time power flow among the modules efficiently. The simulation studies were carried out on different configurations of the modules which include DC sub-grid, single phase stand alone with an inverter and single phase grid-tied with an inverter. This paper further discusses advantages and disadvantages of each configurations.
