Abstract: Efficient power consumption, intelligent power monitoring and interactive control of power consumption in smart homes are the key factors of sustainable development, reduction of power demand peaks and activities related to avoidance of blackout effects. The highlight of the proposed system is its ability to control maximum consuming power of the home appliances (HAs) and keep the total power consumption below a certain limit and allowing the home user more flexibility to operate their HAs based on HA priority. The proposed smart power management system consists of smart electric sensors (SESs) and power provisioning controller (PPC). The PPC and SES are concurrently used to control and maintain stability and complete power waveform behavior examination. However, we need to reassign an amount of consuming power from one HA to another when the ON/OFF status of HA changes. This paper offers a system to control the maximum power consumption considering heterogeneous HAs with different response speed. In order to guarantee the maximum consuming power limit, we compute the limited suggested power level for HAs. Simulation results show the effectiveness of our system in managing maximum power consumption.

Keywords: Power provisioning controller, smart electric sensor, maximum consuming power, home appliance priority, power supply or demand
