The invention discloses a three-phase imbalance processing method and system based on model predictive control, and belongs to the technical field of data processing, and the method comprises the steps: obtaining historical load data; inputting the historical load data into the space-time diagram convolutional neural network to obtain a short-term current prediction result; calculating a three-phase imbalance continuous accumulation index according to a short-term current prediction result; judging whether the three-phase imbalance continuous accumulation index exceeds a preset value or not; if yes, executing the next step; and carrying out commutation operation through the commutation regulation and control model. According to the invention, a brand new three-phase imbalance continuous accumulation index is introduced, the commutation operation is carried out when the three-phase imbalance continuous accumulation index exceeds a preset value, and the three-phase imbalance continuous accumulation index consid
