Dynamic Analysis of Transient Voltage for Distribution Network with the Consideration of Wind Power

Distributed wind power will bring great impact on transient voltage of distribution network. Based on the characteristics of distributed wind power, this paper presents a doubly-fed induction Generator with four wind speed model and Crowbar protection model in DigSILENT/PowerFactory. The analysis is carried out for a test distribution system representative of the Benchmark 20kv grid. Firstly, this paper respectively provide simulation results showing the effects of distributed wind power on the dynamic voltage in wind fluctuation and a faulted system. Then, a static synchronous compensator (STATCOM) is used to improve the voltage profile of the distribution system.
