The invention discloses a photovoltaic inversion controller's parameter identification method based on the fuzzy C mean value and the differential evolution hybrid algorithm. The method comprises: 1) setting the three-phase short-circuit fault disturbance at the grid connection point of the photovoltaic inverter; and sampling the active power output of the photovoltaic inverter; 2) identifying all control parameters of the photovoltaic inverter through the use of the fuzzy C mean value and the differential evolution hybrid algorithm wherein the identification results of the voltage outer ring proportional coefficient, the voltage outer ring integral coefficient, and the current inner ring proportional coefficient are the final results of the parameters; 3) setting the photovoltaic direct current voltage reference value sudden disturbance and sampling the active power output of the photovoltaic inverter again; and 4) through the use of the fuzzy C mean value and the differential evolution hybrid algorithm, identifying the current inner ring proportional coefficient and the filter inductance parameters. The method of the invention is able to obtain the parameter values of a photovoltaic inversion controller quickly and accurately so that the simulated dynamic response curve of the photovoltaic inversion controller is consistent with the actually measured dynamic response curve.
