Research and application of trans-regional cooperative disposal of UHV interconnected power grid

With the rapid construction of UHV AC/DC power grid, the integration characteristics of power grid are becoming more and more prominent, and real-time operation control of dispatching is significantly becoming more and more difficult. The existing monitoring and control model based on the system model data cannot meet the requirements for the development of UHV power grid. Based on the existing achievements of dispatching automation system, the general goal and framework of the trans-regional cooperative disposal of UHV interconnected power grid are put forward, and the key technologies are analyzed in four aspects: situation awareness, fault location, joint disposal and cooperative control to provide reference and example for follow-up construction for real-time control and support system for the dispatching of UHV power grid.
