Abstract:As carbon peaking and carbon neutrality targets steadily progress, the increase of integrated energy microgrids will form microgrid clusters, namely, multi-microgrids integrated energy systems. For the multi-microgrids integrated energy system with electrical energy interaction, an optimal dispatching model for the multi-microgrids integrated energy system with electric power interaction considering efficient utilization of energy cascades is proposed. First, the architecture of the multi-microgrids integrated energy system and the energy quality coefficient method are described in detail. Then, considering economic and energy efficiency objectives, an optimal dispatching model for the multi-microgrids integrated energy system considering efficient utilization of energy cascades is constructed. Finally, through case analysis, the rationality and effectiveness of the proposed solution are demonstrated, which significantly improves energy efficiency while ensuring high economic efficiency.
