Factory power management and control system and method based on edge-cloud coordination

A factory power management and control method based on edge-cloud coordination, comprising following steps:

• S1:
• storing an STN task model Mt in production field in the cloud power management center, storing a power generation model Mg, a power storage model Ms, and a power price model Mp of the power supply side in the power supply proxy, and specifying algorithm complexity ranks;
• S2. forming an industrial field network by a field node, a routing node and a device executing production tasks of the device layer;
• S3. parsing, by the field node, production task information data Ip and sending same to an edge node;
• S4:
• issuing, by the cloud power management center, an STN model in production field to the edge node;
• S5:
• sending, by the power supply proxy of the power supply side, the power generation model Mg, the power storage model Ms and the power price model Mp to the edge node;
• S6:
• computing, by the edge node, an electricity demand Ed required to complete these production tasks according to the production task information data Ip and the STN task model Mt;
• S7:
• judging, by the edge node, algorithm complexity ranks according to values of algorithm head O;
• S8:
• judging, by the edge node, data timeliness ranks through attribute values of data frames;
• S9:
• computing, by the edge node, values of comprehensive ranks R according to values of algorithm complexity ranks O and values of the data timeliness ranks TIME_priority;
