| description | The invention discloses a method for evaluating an AC-side impedance balance index of a grid-connected photovoltaic inverter, and the method comprises the steps: building a time sequence of an AC-side impedance balance index evolution system for the grid-connected photovoltaic inverter; carrying out the normalization processing of measurement data according to the above time sequence; carrying out SVM (support vector machine) algorithm processing of the measurement data; and calculating the AC-side impedance balance index of the grid-connected photovoltaic inverter. Through the cooperation of the above four steps, the method can achieve the real-time monitoring of operation parameters and meteorological environment parameters of a power distribution network and a photovoltaic power generation system thereof, carries out the prediction and calculation of the AC-side impedance balance index of the grid-connected photovoltaic inverter according to the monitoring parameters, controls the photovoltaic power genera |
