Low-carbon park group topology prediction and time service method and system based on power line carrier

The invention discloses a low-carbon park group topology prediction and time service method and system based on a power line carrier, and the method comprises the steps: collecting the inter-topology feature data of a low-carbon park, the historical time service time delay of a time service data packet of the power line carrier, and the error data through the power line carrier, and carrying out the prediction of the group topology of the low-carbon park through the back propagation. And the low-carbon smart park group monitoring terminal topology adjacency relation is accurately predicted through the BP neural network. Based on the topological adjacency relation of the monitoring terminals, a time service data packet path selection decision is optimized by adopting a synchronous group game, and time service is further performed on the monitoring terminals and electrical equipment in the park through power line carriers, so that high-precision low-delay wide-coverage time synchronization of the low-carbon sma
