Simulation Analysis of Voltage Transient Stability Margins in Distribution Networks Under Large-Scale Distributed Power Supply Access Conditions

In the traditional distribution network voltage transient stability margin analysis under the conditions of large-scale distributed power supply access, the processing of the analysis index is not refined enough, resulting in large errors in the analysis results. In this regard, a simulation analysis of the voltage transient stability margin of the distribution network under the conditions of large-scale distributed power supply access is proposed. Extraction of key features. Determine the characteristic parameters of the distributed power supply. Calculation of different index units and orders of magnitude and standardisation of the margin analysis index. Output of margin simulation results. The experiments show that the method has a lower error value than traditional methods in both active and reactive margin analysis and is of high application value.
