Design and Application of Standardized Power and Communication Module for Energy Router

Energy Internet (EI) can be viewed as an upgraded version of smart grid. In order to improve the scalability of equipment in EI, a standardized power module (SPM) is designed in this paper. The SPM is based on a power electronic structure through which rectifying, inverting and chopping can be realized. With SPMs, a variety of distributed energy or load can be interconnected. Besides, the authors design a standardized communication module (SCM) to integrate the communication units such as RS485, RS232, Ethernet, CAN and optical fiber, and to coordinate with the SPM. The new energy router (ER) structure based on SPM and SCM can realize power exchange and optimization targets. Aiming at power quality control and lifting voltage level, SPM and SCM can work as modular multilevel converter (MMC) and active power filter (APF). This article provides scheme and simulation verification.
