Grid-connected multi-station fusion comprehensive energy total system based on double-layer energy management

The invention relates to a grid-connected multi-station fusion comprehensive energy total system based on double-layer energy management, which comprises a plurality of comprehensive energy systems, each comprehensive energy system is connected to a main network, and each comprehensive energy system comprises a distributed power supply station, an energy conversion unit and an energy storage station which are mutually connected in pairs, the grid-connected multi-station fusion integrated energy total system adopts a double-layer energy management model to carry out optimization scheduling, the double-layer energy management model comprises a lower-layer planning model and an upper-layer planning model, and the lower-layer planning model aims at minimizing the total energy consumption cost of the system. The upper-layer planning model takes the maximum difference value obtained by subtracting the energy interaction cost between the grid-connected multi-station fusion comprehensive energy total system and the m
