[China Instrument Network Instrument R&D] On January 4, 2017, the active distribution network coordinated control system developed by Guodian NARI Technology Co., Ltd. and Agricultural Power Co., Ltd. was operated in Changzhou, Jiangsu. After obtaining the system's operation, the leaders of the State Grid Jiangsu Electric Power Co., Ltd. and others learned the detailed understanding of the simulation control module and corresponding strategies of the coordinated control system and gave full affirmation.
The active distribution network coordinating control system is the latest product of Guodian Nanrui. This system ensures the safe and reliable operation of the active distribution network through comprehensive coordination and optimization of the adjustable resources of the distribution network such as photovoltaic, energy storage, electric vehicles and flexible loads. Enhance the ability of distributed power sources and diverse loads such as electric vehicles to participate in power grid peaking, and provide powerful technical support for friendly interaction between power sources and loads.
The Changzhou Active Distribution Network Project was established by Changzhou Power Supply Company in accordance with the National Development and Reform Commission's "Guiding Opinions on Promoting "Internet + Smart Energy Development." The active distribution network changes the passive mode of traditional distribution network operation, control and management modes. It will have self-checking and self-healing functions of the power grid faults. That is, after the power line fails, the system can automatically determine the fault point and automatically isolate the fault area. , to achieve a fast recovery power supply in a fault-free area. The realization of coordinated and optimized operation of energy storage, new energy, controllable load, and power grids is of great significance for enhancing the acceptance of distributed energy and diversified loads.
