The invention, which relates to the technical field of micro-grid
energy management, discloses a cooperative
control system for access of an SST directly-hung
overcharge host to a micro-grid, comprising a multi-time scale cooperative control architecture, an AI prediction-optimization module, plug-and-play modular hardware, a bidirectional vehicle-network interaction cooperative
control unit, and a dynamic weight optimization and digital twinning operation and maintenance platform. According to the method, the SST port power instruction is dynamically generated, the self-
adaptive capacity and the overall operation economy of the
system for dealing with the uncertainty of the source and load double sides are remarkably improved, the priority of the optimization target can be automatically adjusted according to the scene through dynamic weight optimization and a digital twin operation and maintenance platform, and the optimization efficiency is improved. According to the method, a control strategy is optimized, a 1: 1 digital twinborn model is utilized to carry out real-time safety
verification and fault pre-judgment on the control strategy, the reliability, safety and operation and maintenance intelligence level of the
system are greatly enhanced, and in addition, through standardized plug-and-play hardware and a V2G cooperation unit, interaction support of on-site consumption of
renewable energy sources and a
power grid is further promoted.
