Space load prediction method and system for rapid power recovery after disaster

The invention discloses a space load prediction method and system for rapid power recovery after a disaster. The method comprises the following steps: determining a pre-prediction time period T1 and a load prediction target time period T2 according to typhoon disaster information; acquiring load data of the power supply grid of the affected area according to the pre-prediction time period T1 and the prediction target time period T2, wherein the load data comprises real-time load data Xc (T1) of the pre-prediction time period T1, historical load data Xh (T1) of the pre-prediction time period and historical load data Xh (T2) of the target prediction time period; based on historical load data Xh (T1) corresponding to a time period T1 before prediction, obtaining a historical typical load curve Ch (T1) of the power supply grid in the time period T1 and a corresponding membership matrix Uh through fuzzy mean value clustering; according to the fuzzy mean value clustering result Ch (T1) and the real-time load data X
