Research and Implementation of a Local Modification Method of Power System Topology Suitable for Large Power Grid Training Simulation System

Abstract

This paper proposes a local topology correction method for large power grid simulation. The analysis method of the local topology corresponding to the “open” and “close” events of the power equipment and the correction method of the corresponding node admittance matrix. This method is suitable for online analysis systems such as large power grid simulation systems. Finally, this paper verifies that the local topology correction method proposed in this paper greatly improves the topology analysis speed and calculation efficiency of the large power grid training simulation system.
