Priority based maximum consuming power control in smart homes

Due to an increase in home appliances (HAs) the overall power consumption in home tends to grow and leads an increasing risk of losing stability. In this paper, we propose a system model for smart homes to control maximum power consumption by HAs based on HA priority. The proposed system consists of smart electric sensors (SESs), power provisioning controller (PPC) and HAs. The role of PPC is to gather ON/OFF status from each HA and instantaneous consuming power level from SES, and to send control signal back to each HA. After gathering information, along with HA priority, computes a final target power level for each HA is not a hard task. However, when ON/OFF status of HAs change, we may need to reassign an amount of consuming power from one HA to another, and the transient behavior due to such reassignment of power is not simple. This paper proposes a system to control the maximum total power consumption in detailed transient behavior considering heterogeneous HAs with different time constants. In order to guarantee the maximum power limit, we will compute the remaining power, and reassign it to HAs as their temporal target power levels. Simulation results show the effectiveness of our system in managing maximum power consumption.
