TL;DR: The automatic standby power cut-off outlet and a ZigBee controller with IR code learning functionality are proposed and designed to reduce standby power consumption and to make the room easily controllable with an IR remote control of a home appliance.
Abstract: This paper proposes remote-controllable and energy-saving room architecture to reduce standby power consumption and to make the room easily controllable with an IR remote control of a home appliance. To realize the proposed room architecture, we proposed and designed the automatic standby power cut-off outlet and a ZigBee controller with IR code learning functionality. The proposed power outlet monitors the power consumption for the predetermined time and completely cuts off the power supply when the monitored power is below the threshold. This power outlet has a function of changing the threshold power, which enables any kinds of home appliances to be applied to the power outlet. To efficiently manage the power outlets and the lights, we proposed the ZigBee controller with IR code learning functionality. The ZigBee controller has several onboard buttons to wake up the power outlets and control the dimming light. By using IR code learning functionality, the ZigBee controller can assign a certain IR code of a remote control of a home appliance to the power outlet or the dimming light. A user can control the power outlets and the dimming light with an IR remote control of any home appliance. Our proposed room architecture provides the remote-controllable and energy-saving room.

TL;DR: This paper provides a comprehensive review on previous and current research related to the HEMS by considering various DR programs, smart technologies, and load scheduling controllers.
Abstract: The increasing demand for electricity and the emergence of smart grids have presented new opportunities for a home energy management system (HEMS) that can reduce energy usage. The HEMS incorporates a demand response (DR) tool that shifts and curtails demand to improve home energy consumption. This system commonly creates optimal consumption schedules by considering several factors, such as energy costs, environmental concerns, load profiles, and consumer comfort. With the deployment of smart meters, performing load control using the HEMS with DR-enabled appliances has become possible. This paper provides a comprehensive review on previous and current research related to the HEMS by considering various DR programs, smart technologies, and load scheduling controllers. The application of artificial intelligence for load scheduling controllers, such as artificial neural network, fuzzy logic, and adaptive neural fuzzy inference system, is also reviewed. Heuristic optimization techniques, which are widely used for optimal scheduling of various electrical devices in a smart home, are also discussed.

TL;DR: More efficient home energy management system to reduce power consumption in home area and provides easy way to add, delete, and move home devices to other power outlets is described.
Abstract: This paper describes more efficient home energy management system to reduce power consumption in home area. We consider the room easily controllable with an IR remote control of a home device. The room has automatic standby power cut-off outlets, a light, and a ZigBee hub. The ZigBee hub has an IR code learning function and educates the IR remote control signal of a home device connected to the power outlet. Then the power outlets and the light in the room can be controlled with an IR remote control. A typical automatic standby power cut-off outlet has a waiting time before cutting off the electric power. It consumes standby power during that time. To eliminate the waiting time, we turn off the home device and the power outlet simultaneously with an IR remote control through the ZigBee hub. This method actively reduces the standby power. The proposed HEMS provides easy way to add, delete, and move home devices to other power outlets. When a home device is moved to the different outlet, the energy information of the home device is kept consistently and seamlessly regardless of location change. The proposed architecture gives more efficient energy-saving HEMS.

TL;DR: Intelligent cloud home energy management system (iCHEMS) assigns dynamic priority to a household appliance according to the type of appliance and its current status, and reduces the average total power consumption by up to 7.3 percent.
Abstract: Recent advances in micro-grid and distributed renewable energy have facilitated more efficient home energy management systems. However, due to characteristics of renewable energy such as intermittent energy generation, home energy management systems are inefficient and the recent systems therefore cannot be successfully applied to existing home. Therefore, this paper proposes intelligent cloud home energy management system (iCHEMS), considering these issues. iCHEMS assigns dynamic priority to a household appliance according to the type of appliance and its current status. In accordance with the assigned priority, the use of household appliances is scheduled considering renewable energy capability. We implemented iCHEMS in the test bed and conducted an experiment to verify the efficiency of the proposed system. The results show that the proposed system reduces the average total power consumption by up to 7.3 percent.

TL;DR: The technical considerations and system requirements necessary when implementing a low-cost low-power wireless personal area network are discussed and an overview of the unique applications such a technology will enable are provided.
Abstract: A low-rate wireless personal area network, or LR-WPAN, is a network designed for low-cost very-low-power short-range wireless communications. Until now, the main focus in the wireless industry has been on communications. Until now, the main focus in the wireless industry has been on communication with higher data throughput, leaving out a set of applications requiring simple wireless connectivity with relaxed throughput and latency requirements. LR-WPANs will connect devices that previously have not been networked and allow applications that cannot use current wireless specifications, including applications in fields such as industrial, agricultural, vehicular, residential, medical sensors and actuators. TaskGroup 4 of the IEEE 802.14 Wireless personal Area Network working group is currently working to define a wireless communication standard for LR-WPANs. This article discusses the technical considerations and system requirements necessary when implementing a low-cost low-power wireless personal area network and provides an overview of the unique applications such a technology will enable.

TL;DR: The WPCOM integrates the multiple AC power sockets and a simple low-power microcontroller into a power outlet to switch the power of the sockets ON/OFF and to measure the power consumption of plugged electric home appliances.
Abstract: In this paper we describe the Wireless Power-Controlled Outlet Module (WPCOM) with a scalable mechanism for home power management which we have developed. The WPCOM integrates the multiple AC power sockets and a simple low-power microcontroller into a power outlet to switch the power of the sockets ON/OFF and to measure the power consumption of plugged electric home appliances. Our WPCOM consists of six scalable modules, that is, the Essential Control Module, the Bluetooth Module, the GSM Module, the Ethernet Module, the SD Card Module and the Power Measuring Module, which together provide an indoor wireless, and an outdoor remote control and monitor of electric home appliances. We have designed a PDA control software and remote control software which support the Graphic User Interface, thus allowing the user to easily monitor the electric home appliances through the PDA and the Internet individually. In addition, we use a Short Message Service to achieve control and monitoring through a GSM cellular mobile phone for remote use anytime and anywhere.

TL;DR: This paper describes a network architecture for home energy management system (HEMS) that gives appliances network-ready capabilities without increasing cost and proved effective in the field evaluation of HEMS.
Abstract: This paper describes a network architecture for home energy management system (HEMS). To realize HEMS, networked appliances with control/monitor capabilities and home network without new wiring are indispensable. However, appliances with no expansive functions and conventional power-line carrier communication deteriorated by its interference have made it difficult to built advanced HEMS. We propose network architecture to solve these problems. The network capability is divided to, minimum interface software embedded in appliance and a separated network adapter. This architecture gives appliances network-ready capabilities without increasing cost. Dispersed-tone power line communication (DTPLC) was also developed for no-new-wire network. DTPLC modem avoids narrow-band power line noise and co-exists with conventional narrow-band power line communication. Network adapter with DTPLC modem was implemented and the network architecture proved effective in the field evaluation of HEMS.

TL;DR: In this article, the authors proposed a closed-loop standby voltage scaling scheme for V/sub DD/ to near the point where state is lost, which can provide over 2/spl times/ higher savings than an optimal open-loop approach without loss of state.
Abstract: Lowering V/sub DD/ during standby mode reduces power by decreasing both voltage and current. Analysis of flip-flop structures shows how low the voltage can scale before destroying the state information. Measurements of a 0.13-/spl mu/m, dual-V/sub T/ test chip show that reducing V/sub DD/ to near the point where state is lost gives the best power savings. We show that "canary" flip-flops provide a mechanism for observing the proximity to failure for the flip-flops. The canary flip-flops enable closed-loop standby voltage scaling for achieving savings near the optimum. This approach potentially provides over 2/spl times/ higher savings than an optimal open-loop approach without loss of state.
