Data synchronization method and device of power grid business processing system and business processing system

The invention relates to the technical field of electric power, and provides a data synchronization method and device of a power grid business processing system, the power grid business processing system and a storage medium. The power grid business processing system comprises a first processing system and a second processing system; the method comprises the following steps: receiving a power gridservice processing request sent by the first processing system after being triggered by a user; calling a preset micro-service component corresponding to the power grid service processing request forprocessing to obtain first power grid service data, generating a data updating event carrying the first power grid service data, and sending the data updating event to a first processing system through a preset event synchronization interface; and triggering the first processing system to replace second power grid service data stored in a power grid service database of the first processing systemaccording to the first pow
