Implementing a 3-layer communication architecture for AC&DC hybrid smart microgrid

Since there are many convertors, invertors, bidirection convertors, sensors and meters in the AC&DC smart micro-grid system, how to collect the real-time data from these devices and send the control command to them to carry out the remote optimization control in high-efficiency is the main problem the smart micro-grid communication system need to face and solve. In this paper, a 3-layer communication architecture is designed for AC&DC smart micro-grid. In this system, we use different communication method to solve the problem that there are many different devices with different type communication protocol. Finally, we built up the demo system in our lab and realize the function that the data from different terminal device can be transform to central control system and the control command can be send to terminal devices more reliability and effectively, which can provide an useful demo for development of AC&DC hybrid smart micro-grid control and monitoring system.
