The application relates to the technical field of smart grid communication, and discloses a smart substation path controllable network system and method based on IPv6 and white box switching. A centralized controller is used to gather link state information of each white box switch to construct a global topology view. Based on the view and a service demand vector, network service flow is optimized and evaluated to generate a path planning table. Then, the path planning table is translated and coded by a rule conversion module, and is sent to a programmable data plane of the switch through a southbound interface and is solidified into a hardware forwarding table. According to the path planning table, an access side switch matches a received original service packet, generates an IPv6 encapsulated packet with a path strategy expansion header, and finally performs destination address overwrite and hop-by-hop controllable forwarding along the path indicated by the expansion header to obtain a target service packet. In this way, the closed architecture of traditional underlying equipment is broken, and accurate control and high-reliability deterministic flexible transmission of the end-to-end path of massive service in a substation are realized.

This invention relates to a smart grid communication optimization method based on HPLC and HRF dual-mode communication, characterized by the following steps: S1: Acquire and preprocess grid communication data; S2: Based on the preprocessed smart grid communication data, automatically extract dual-channel time-frequency domain features using a feature extractor based on a deep neural network, and dynamically weight the feature importance of different modes through an attention mechanism to obtain a fused unified channel state matrix (CSM); S3: Construct a routing strategy model based on reinforcement learning, and obtain the optimal path decision based on the CSM matrix, grid network topology, and service priority labels; S4: Based on the path obtained from the optimal path decision, adopt adaptive modulation and coding to obtain the optimal modulation and coding scheme and dynamically adapted channel conditions; S5: Perform communication based on the optimal modulation and coding scheme and dynamically adapted channel conditions. This invention significantly improves the communication state awareness capability in complex scenarios.
