Comparative Stability Analysis of a DC Distribution System for Power System Integration of Plug-In Electric Vehicles

Abstract

DC power distribution systems have the advantages of minimal external noise, low power loss, huge power capacity, and excellent quality when compared to AC power distribution systems. In the future, the DC distribution system will be an important development path for the urban power distribution system, and the charging and discharging requirements of electric vehicles will have a significant impact on the system's stability. In the context of a DC distribution system. First, integrated stability models of electric car DC distribution systems were installed in various charge/discharge modes, and the DC distribution systems' stability was compared during the process. The Nyquist stability criteria are used to the charging and discharging procedures Is distinct. Finally, using the simulation software MATLAB, an example is generated in the time domain of a DC power distribution system with an electric vehicle, and the simulation results corroborate the theoretical analysis. Therefore, the FUZZY controlled DC distribution system has become a new development direction for the future urban power distribution system, and this project provides a comparative study of the existing method.
