Topology Design and Multi Condition Simulation Analysis of Flexible Interactive System in Low Voltage Distribution Station Area

Currently, with the continuous increase in the proportion of renewable energy on the user side and the increasingly prominent trend of load diversification, the power supply capacity and power quality of traditional distribution networks are being challenged. Meanwhile, with the rapid development of power electronics technology, flexible DC technology based on voltage source converters is gradually being widely applied in power systems. In this context, the topology design of the flexible interactive device and system in the low-voltage substation area based on the analysis of the current power supply and demand in the low-voltage substation area is first completed in this article. Afterwards, the simulation model of the system was built, and its operating results under various common working conditions were provided. Finally, the design and operation of flexible interactive systems are summarized and future development trends are discussed, providing reference for their practical promotion and application.
