Abstract
In order to reduce the complexity of traditional methods, a PCI (Proportional Complex Integral) controller is adopted to control SVG under unbalance-grid condition, which has better performance than PI controller to eliminate steady-state error to compensate nonlinear loads. Based on the αβ frame, the proposed control scheme considerably reduces total algorithm complexity. The current control loop is designed based on mathematical modeling under unbalanced conditions. Simulation and experimental results are provided to validate the correctness of the proposed methods.
