Load prediction method and related device

The invention discloses a load prediction method and a related device. The method comprises the following steps: acquiring related load current, target air temperature and target weather value at preset moments before a target moment; inputting the related load current, the target air temperature and the target weather value into a preset load prediction network model for load prediction to obtain an initial load prediction value; based on BP network model prediction operation, calculating a probability transfer matrix and an initial error prediction value according to related load current; calculating a target error predicted value based on the probability transfer matrix and the initial error predicted value; and calculating a target load predicted value according to the initial load predicted value and the target error predicted value. The technical problems that in the prior art, analysis of environmental factors influencing load performance is lacked, and the prediction effect on irregularly-changed load
