The embodiment of the invention provides a power system online load flow calculation method supporting multi-source real-time data fusion. The method comprises the following steps: acquiring first power data of a power system at first current time; performing load flow calculation on the first power data to obtain initial power prediction data corresponding to the first power data, and obtaining second power data of the power system at a second current time; and performing load flow calculation on the second power data and the initial power prediction data to obtain target power prediction data, taking the target power prediction data as new initial power prediction data, and returning to execute the step of obtaining the second power data of the power system at the second current time. The number of times of load flow calculation reaches a preset number-of-times threshold value; and obtaining a power system state prediction result according to the target power prediction data. According to the method provide
