With the increasing capacity connecting to the grid, distributed power had more and more evident impact on the regional distribution network. In order to realize safe, reliable, efficient and flexible operation of distributed power, a distributed energy microgrid system is proposed. By collecting and processing data, the system provides comprehensive information on equipment operation and fault event records. The system optimizes the operation and analyzes the accident by using these data. Making use of the perfect programmable logic capability, the system achieves mode conversion of microgrid and various control strategies flexibly. Since distributed power connects to the grid, the micro-grid can quickly reach power balance and frequency stability to improve the operational reliability of the distribution network.
