Scheduling task execution method and device, computer equipment, storage medium and computer program product

The invention relates to a scheduling task execution method and device, computer equipment, a storage medium and a computer program product. The method is applied to a main node, the main node is a node selected from clustering center nodes of each cluster, and the method comprises the following steps: receiving a scheduling instruction and a digital signature broadcast on a block chain; the scheduling instruction is generated by a control center of the virtual power plant according to a power scheduling task; performing signature verification on the scheduling instruction based on the digital signature; if the verification is passed, receiving a power generation threshold value reported by each clustering center node, and generating a preprocessing message according to the scheduling instruction and the power generation threshold value; the preprocessing message comprises target scheduling information of each cluster; and generating a block on a block chain by using the preprocessing message, and broadcastin
