Abstract: At present, the AC scheme architecture is complex, the degree of intelligence is low, and it is impossible to unify the coordinated control. In view of this problem, this paper proposes the research and development of digital energy fusion terminal equipment based on artificial intelligence technology, which deeply integrates energy production, transmission, consumption and storage, and realizes the optimal scheduling and management of energy system through digital technology. Combined with practical engineering cases, it effectively solves the problem of unified coordinated control of traditional AC distribution network, and has a good promotion prospect.
