Abstract
Traditional AC distribution networks generally have issues with power quality and reliability,while flexible DC distribution networks can effectively solve such problems.Active loads such as distributed new energy and energy storage systems are important components of flexible DC distribution networks.Modeling and analyzing active loads can help promote research in DC distribution network flow analysis,voltage control,and other aspects.A control model-based active load modeling method was proposed.A power voltage characteristic model for active loads was established,which simplifies the variation characteristics of power electronic components in active loads on a small time scale and reflects the power voltage characteristics of active loads on a second scale.This greatly reduces the computational complexity in computer simulation of DC distribution networks.The simulation model can run quickly and highly restore the electrical characteristics of active loads.An active load model was built using MATLAB/Simulink,and its characteristics were verified.The influence of the length of the line from the active load to the DC distribution network on its power characteristics was studied.关键词
