Linear power damping synchronizing controller mechanically synchronizes with VSC to grid which enables full power injection under weak grid condition providing by damping with controllers stable and smooth operations also. But whenever sudden large disturbances occur in the system this controller may leads to affect the system stability. To overcome this difficulty a nonlinear controller is implemented. Thus the linear controller needs a nonlinear controller to improve the system stability under transient conditions. Nonlinear controller is used to supplement the linear controller and enhances the system stability and performance under large disturbances such as self-synchronization, disturbances in grid frequency, high power injection in very weak grids and fault ride through conditions. The main theme of this project to develop a new controller topology to connected to a voltage source converter to weak grids. The controller has two parts Linear power damping synchronizing controller. Non-linear controller
