An economic dispatching method for an AC/DC hybrid micro-grid considering prediction errors belongs to the field of AC/DC hybrid micro-grid. The economic dispatching method includes a day-ahead dispatching stage, an intra-day pre-dispatching stage and an intra-day dispatching stage. The day-ahead dispatching stage includes the following contents: (1) a day is divided into 24 periods according to hours, and the power output and absorption of each distributed unit in each period are fixed; (2) the generating power of wind turbines, the photovoltaic generating power, the fluctuation of AC important loads and the fluctuation of DC important loads in each period of the next day are predicted; and (3) a mathematical model of distributed generation is established. The problems of incomplete consideration of the operation state of the AC-DC hybrid micro-grid in the existing research, errors in prediction of the distributed generation and load of the AC-DC hybrid micro-grid, and difficulty in realizing intra-day economic dispatch of the AC-DC hybrid micro-grid are solved.
