Collaborative Architecture and Applications for Main Grid and Distribution Network Dispatching Transactions Adapting to High Ratio Access of Distributed New Energy
Xinfan Jiang, Yonggang Liu, Jinbo Wu, Juan Huang · 2024
The proportion of new energy installed capacity and power generation connected to the distribution network in China is increasing year by year. Due to the volatility, randomness, and unpredictability of new energy, the flow fluctuations in the distribution network are more frequent, and the coupling between the main grid and the distribution network is further prominent, leading to increased operational risks in the power grid. There is an urgent need to improve the existing dispatching automation system architecture and application functions to improve the coordination of between the main grid and distribution network dispatch transactions. This paper designs a technical architecture that adapts to the integrated management of the main grid and distribution network models, and develops applications such as topology analysis, power supply path analysis, power supply range analysis, power flow calculation, loop analysis, and operation mode optimization for the coordination between main grid and distribution network dispatch transactions. The technical architecture and collaborative applications have been successfully applied in the power grid dispatch automation system.
