Robust Control Scheme for a Grid Connected DG System under Weak Grid Conditions, M.Sc. Thesis Sharif University of Technology ; Namvar, Mehrzad (Supervisor) ; Karimi, Hoshang (Supervisor)
Abstract
Three-phase voltage source converter (VSC) is vastly utilized in the renewable energy resource and distributed generation (DG) systems interface units due to its high controllability and flexibility. Because of the high nonlinear nature of the system, the gird-connected inverter shows poor performance if the conventional control scheme are used. In this thesis, a new control scheme based on backstepping strategy is presented for control of a grid connected DG systems. The proposed scheme is responsible for regulating the active and reactive power components of the VSC power of the DG system. The VSC of the DG system is connected to a stiff utility grid through an L-type filter. In the first...
