This paper presents a novel home area energy management system (HEMS) for smart homes with different load profiles installed with photovoltaic generation

energy storage

and DC demand. The developed HEMS is shown to optimize the utilization of local renewables while minimizing energy waste between AC and DC conversions and between storage charging and discharging. Previous studies on HEMS have not considered the impact of load types. In this study

the performance of the proposed HEMS is demonstrated on different smart homes with and without electric heating. A comparative study is carried out to investigate battery behavior

characteristics of AC and DC conversion

and benefits that customers receive. A sensitivity analysis is also conducted to discuss the effects from varied energy storage capacities

AC/DC conversion efficiencies

and PV output. The results show that cost reduction in energy bills can be greatly impacted by load profiles

and customers with electric heating load coupled with sufficiently large energy storage would receive the most reduction in their energy bills.
