Molldeing and Simulation of a Small-Scale Wind Turbine Generator in Isolated Distribution Network

In recent years, the wind energy capacity is rapidly increasing in importance as a share of electricity supply on worldwide basis. A small-scale wind turbine generator is usually installed in an isolated distribution network. This paper aims to justify that the intermittent power output of a small capacity of wind power contributes to supply demand without interfering with the output power balance and voltage profile of the network. A d-q axis model of an isolated distribution network is established with connection of a doubly fed wound rotor type induction generator (DTIG)-based wind turbine generation. By using Mathlab Simulink, the simulation results demonstrated that a small-scale of wind turbine generation unit can be freely operated in an isolated distribution network without creating violation in power balance and voltage profile.
