Research on SVG Control Based on Grid Voltage Tracking

With the increasing tension of energy and the increasing pollution of the environment, wind energy is used as a clean energy source for power generation. Because natural wind is uncontrollable and difficult to store, it is difficult to control output power like conventional energy generation. In this paper, a new Static Var Generator (SVG) control scheme is proposed. This scheme directly uses the grid-side voltage as the modulation wave to compare with the carrier wave to generate an Sinusoidal Pulse Width Modulation (SPWM) control signal to drive the SVG. After simulation in Matlab (Simulink) and Multisim, this method can not only ensure the smooth connection of SVG to the grid, but also compensate the reactive power required by the grid.
