Research and Application of Constructing a Comprehensive Dynamic Topology for Distribution Networks Based on a Real-Time Measurement Center

With the rapid development of massive distributed energy resources integration and load demand-side response in the power grid, distribution network power flows have become bidirectional, and the grid topology has exhibited characteristics of complexity, high-dimensionality, and multi-state. This has created an urgent need for comprehensive dynamic topology service capabilities, bringing new challenges in areas such as topology data mapping, topology state synchronization, and full-domain topology computation. In response to these needs, this paper investigates the technology for constructing and maintaining power grid topology and proposes a method for constructing a comprehensive dynamic topology for distribution networks based on a real-time measurement center. By integrating measurement data with distribution network topology information, a fine-grained foundational topology model is constructed, which is then dynamically adjusted based on real-time switch state information to form a comprehensive dynamic topology. This approach effectively supports the business analysis needs of multiple dimensions and multiple time states, aiming to enhance the grid's response speed and processing performance.
