Automatic Service Discovery in Universal Plug and Play

The home network technologies are taking advantage of the increasingly promising market prospect, thank to the popularity of digital home appliances. To enable control and data transfer among interconnected home network devices, it is necessary to adopt the Universal Plug and Play (UPnP) technology. This technology leverages the Internet technical standards including the Internet Protocol (IP), the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), the Hypertext Transfer Protocol (HTTP), and the Extensible Markup Language (XML) to provide the automatic across-platform service discovery and the remote control. In addition to the control and the data transfer among networked devices, the UPnP provides the flexible and robust service discovery ability to change the complex network device drive into a simple remote network control.

Research on Plug and Play of IED in Smart Substations

This paper focus on the problems with smart substations such as long period of construction and design, difficulties of debugging and maintenance. According to the whole process of designing, construction, operation and maintenance of smart substations and characteristics of IED, the plug and play technology on the whole life cycle of a smart substation is proposed. Standardized virtual terminal description is used in matching the signals, standardized definitions and order of virtual terminal is used in connecting the signals, and management server is used in managing IED failures and backup. The plug and play technology can effectively improve the efficiency of design, construction, operation and maintenance of smart substations.

Distributed energy storage node controller and control strategy based on energy storage cloud platform architecture

Based on the energy storage cloud platform architecture,this study considers the extensive configuration of energy storage devices and the future large-scale application of electric vehicles at the customer side to build a new mode of smart power consumption with a flexible interaction,smooth the peak/valley difference of the load side power,and improve energy efficiency.A plug and play device for customer-side energy storage and an internet-based energy storage cloud platform are developed herein to build a new intelligent power consumption mode with a flexible interaction suitable for ordinary customers.Based on the load perception of the power grid,this study aims to investigate the operating state and service life of distributed energy storage devices.By selecting an integrated optimal control scheme,this study designs a kind of energy optimization and deployment strategy for stratified partition to reduce the operating cost of the energy storage device on the client side.The effectiveness of the system and the control strategy is verified through the Suzhou client-side distributed energy storage demonstration project.

QKD system with fast active optical path length compensation

We develop a quantum key distribution (QKD) system with fast active optical path length compensation. A rapid and reliable active optical path length compensation scheme is proposed and applied to a plug-and-play QKD system. The system monitors changes in key rates and controls it is own operation automatically. The system achieves its optimal performance within three seconds of operation, which includes a sifted key rate of 5.5 kbps and a quantum bit error rate of less than 2% after an abrupt temperature variation along the 25 km quantum channel. The system also operates well over a 24 h period while completing more than 60 active optical path length compensations.
