Design and implementation of communication network and system management for hybrid AC/DC microgrid module

摘要

In this paper, an adaptive integrated hybrid AC/DC microgrid module is proposed to accommodate a wide range of Distributed Renewable Energy Resources (DRERs), Distributed Energy Storage Devices (DESDs) and Distributed Demand Resources (DDRs) into the existing distribution systems. The concept and the architecture of adaptive integrated hybrid AC/DC microgrid module have been elaborately explained. This microgrid module is designed to be portable, scalable, easy of deployment, and simple of operation. Thus a number of microgrid modules can form a microgrids constellation. The modeling of the proposed microgrid module based on IEC 61850 standard is presented. To achieve the target of plug-and-play functionalities, specific Microgrid Module Communication Network (MMCN) and Microgrid Module Operating System (MMOS) are designed and implemented in the hardware prototype built in the laboratory. Experimental results obtained from the lab prototype clearly validate the effectiveness of the proposed design of the microgrid module, communication network and operating system.
