Research On Multi - Time Scale Modeling And Simulation Technology For Ac/Dc Hybrid Distribution Network

AC / DC hybrid distribution networks need to be simulated at different time scales in specific scenes. In this paper, based on the different particle size of the model, a multi-time scale simulation model of AC / DC hybrid distribution network is established on the basis of establishing the mathematical model and control strategy of the converter component of AC / DC hybrid distribution network. Based on the IEEE 33-node example, Matlab / Simulink is used to simulate the running process of AC / DC hybrid distribution network at each time scale, and the accuracy of the simulation results is compared with each time scale. The experimental results show that the simulation waveform of AC / DC hybrid distribution network model is more accurate.
