Dispatch Management Methods for Enhancing New Energy Accommodation Capacity in Distribution Networks

In order to actively implement the dual carbon target and resolutely fulfill mission responsibilities, power grid companies continuously innovate in serving the development of new energy industry, focusing on exploring innovative dispatching management methods to enhance new energy accommodation in distribution networks, and accumulating practical experience. The company have successfully established a distribution network dispatch management system that integrates five aspects: constructing a new energy data ledger system, analyzing the impact of new energy access, strengthening the reliability of power supply, strengthening the analysis and identification of load characteristics, and exploring the interactive application scenarios of source-network-Ioad. The power grid company has efficiently implemented the requirements of new energy dispatch and management, promoted the significant improvement of production benefits, improved the capacity of power supply assurance and supply increase, and successfully achieved a stable peak summer season for the power grid. In 2022, in the Tianjin area where the dispatch management method is implemented, 15 new energy projects such as distributed photovoltaic are successfully connected to the grid, and there are no light abandonment events caused by primary and secondary equipment failures, defects and other reasons on the grid side, ensuring the full absorption of new energy.
