Abstract Electronic-Interface (EI) is used in the micro-grid to connect the distributed generator (DG) with the bulk grid, and the stability of itself and its effect on the grid is of great importance. Traditional control methods have some different disadvantages. This paper presents a nonlinear control method based on the accurate linearization. This method transfers the nonlinear problem to a normal linear one use specific nonlinear transformation, resulting in the final control of the whole nonlinear system. This paper tests the robust control characteristic of this method. This paper controls the power output of the DG, compared with the conventional PQ control method. The experiment results of the simulation on the PSCAD/EMTDC show the correctness and advantage of the nonlinear control method.

Key words： Nonlinear control accurate linearization power control robust control
