Static var generation (SVG) has been widely used in distribution networks due to its reactive power compensation and voltage stabilization. In order to reduce the high-order harmonics generated during SVG operation, an LCL filter is usually employed on the grid side of the converter. However, the LCL filter easily excites resonance and worsens stability and performance of SVG. Therefore, this paper proposes a three-loop control (TLC) method for SVG with LCL filter, which combines virtual impedance method to improve the dynamic and static characteristics and alleviate the resonance.
