Upper-Middleware Development of Smart Energy Profile 2.0 for Demand-Side Communications in Smart Grid

In smart grid, demand-side communications play a significant role in real-time applications, such as demand response and advanced metering. With recent progresses on Internet-of-Things (IoTs), different communication technologies are available for the demand side, such as ZigBee, Bluetooth, Wi-Fi, etc. To improve the inter-operability of various IoTs in demand side of smart grid, ZigBee and Homeplug Alliances have jointly developed the Smart Energy Profile 2.0 (SEP 2.0) as the upper-layer communication protocol, which has been approved as an international standard, namely IEEE 2030.5. Despite of its promising application in demand side, the development on constrained IoT devices is challenging. To address this issue, an upper middleware for SEP 2.0 standard is developed based on the SimpleLink Wi-Fi technology of Texas Instruments (TI). It enables SimpleLink Wi-Fi devices to support SEP 2.0-based communications in the demand side of smart grid. In the end, an experimental system is built to demonstrate the effectiveness of the presented upper middleware.
