Multi-criterion Analysis of Selected Power Management Strategies in Smart Home Systems

“…Multi-criterion analysis results for the two developed smart home energy management system solutions show that the combination of energy management system and renewable energy source brings material effects, providing energy savings of at least 11-31% [Horyński 2015], and when they are focused on a specific group of devices, an energy demand reduction of up to 60% can be achieved, although with a much lower convenience level. With a properly configured smart home energy management system (use of energy storage), independence from the external energy grid (zero-energy building) can also be achieved.…”

“…0.7 kWh for each 1 kWh given to the power grid (option for installations with power above 10 kWp) during a settlement period of 12 months. If energy from a photovoltaic installation were used for the purposes of a house, it could be expected that about 20% of the annual power demand of the other home appliances would also be covered from the photovoltaic installation (estimate based on [Horyński 2015]). This resulted in a consumption of about 1865.95 kWh for household needs, with the remaining 7463.79 kWh transferred to the power grid.…”
