The Quality Analysis of Electric Energy after Wind Power Grid Integration

Abstract

The electric energy quality problems caused by the running of wind power grid integration such as flicker and harmonic wave are increasingly prominent with the increase of the proportion of wind power. This paper describes the impact of the wind turbine connected to the power grid on the electric energy quality and conducts a trial test and proposes measures to improve the quality of electric energy such as improving the grid structure, improving voltage level of wind farm access system and the application of dynamic reactive compensation to the SVC and so on.
