Abstract
This paper introduces a transmission optimization algorithm for wireless transmissions between smart load controllers and a corresponding gateway in wireless personal area networks, where smart load controllers connect several electrical appliances through their corresponding load interfaces, measure the power consumption from each electrical appliance connected to the load controller, and control on/off switching through its load interface. The aim of this paper is to reduce the traffic load of power consumption data in electrical appliances used in the building area network and the smart grid network. The proposed algorithm allows the smart load controller to efficiently reduce traffic load even if watt-hours calculated in the smart load controllers are the same as the watt-hours in the gateway and the errors of the present values of power consumption interpreted in the gateway fall under the typical tolerance allowed in the specifications of manufacturers of watt-hour meters used in the electrical power industry.
Highlights
The emergence of electric vehicles and increased use and popularity in smart electrical appliances has brought forward the importance of appropriate energy management methods as well
The quality of service (QoS) of building energy management system (BEMS) traffic is an important issue because the historical data of power demand can be incomplete and outdated due to the loss and delay of data transmitted from electrical appliances [6]
It should be noted that the errors of the present values of power consumption fall under the typical tolerance and comply with the specifications of manufacturers of watt-hour meters used in the electrical power industry, and watt-hours calculated in the smart load controllers are the same as the watt-hours in the gateway
Summary
The emergence of electric vehicles and increased use and popularity in smart electrical appliances has brought forward the importance of appropriate energy management methods as well. There is an intelligent electricity network that integrates the actions of all users connected to it and makes use of advanced information, control, and communications technologies to save energy and reduce cost [2]. The quality of service (QoS) of BEMS traffic is an important issue because the historical data of power demand can be incomplete and outdated due to the loss and delay of data transmitted from electrical appliances [6]. As wireless communications for the smart grid will connect a number of electrical appliances and systems together, the optimal network design is an important issue [6]. Compared to single load interface architecture, the smart load controller architecture reduces the number of nodes as many load interfaces as employed, compared to single load interface architecture
