Modeling and Simulation Analysis of Hybrid AC/DC Distribution Network Based on Flexible DC Interconnection
摘要
Abstract
Hybrid AC/DC distribution network detailed modeling and simulation analysis of multi-operation conditions will effectively support reliable and stable operation of active distribution network project. However, at present, large-scale system-level simulation of hybrid AC/DC distribution network based on flexible DC lacks of timeliness and practicability. Based on real-time digital simulation on RT-LAB platform, an active power distribution network model is established, including detailed modeling of a ±20kV flexible DC interconnection system, distributed photovoltaic, wind power, energy storage system, electric vehicle and the corresponding converter control detailed modeling. In view of limitation of energy storage system balance, flexible DC interconnection is applied to active distribution network to provide power supply when power gap occurs. Conditions of accommodation mode of the energy storage system, power supply through flexible DC interconnection from external power grid were simulated and analyzed. The model verifies validity of system application in distribution network. RT-LAB real-time simulation platform highlights its advantage of timeliness in large scale system level simulation. This paper provides preliminary design reference for hybrid AC/DC distribution network construction.关键词
