Analysis of the Influence of SVG Control Parameters on the Effect of Voltage Flicker Compensation

Voltage fluctuations caused by time-varying loads in the power system can cause voltage flicker. Extracting the components that cause voltage flicker in the load and compensating the extracted instructions to the power grid through SVG can achieve the effect of flicker suppression. Instruction extraction and compensation strategies affect the flicker suppression effect. The article introduces three compensation strategies, compares their compensation effects, and analyzes the impact of high pass filter cutoff frequency and SVG current loop width on flicker suppression in instruction extraction.
