Study on the Influence of Large-Scale Wind Power Connecting to Power Grid on Voltage Quality Control

Abstract

As a kind of clean renewable energy, wind power has important application value in the power generation industry. Wind power grid-connected has become one of the important development trends of new energy power generation. Based on large-scale wind power projects, in-depth research on the control of voltage quality in the paper is conducted by large-scale wind power grids. The influence of wind power generation on power quality of power grid is analyzed, and the problems of voltage fluctuation, flicker and harmonics are taken as research objects. Voltage fluctuation and flicker suppression techniques, and power harmonic suppression techniques have been studied as control methods for improving voltage quality. The experimental results prove that the research content of the paper has a good application effect, and it guarantees the voltage quality control for large-scale wind power access to the power grid.
