Multi-mode switching optimization control method for low-voltage flexible interconnection system

A multi-mode switching optimization control method for a low-voltage flexible interconnection system belongs to the technical field of flexible interconnection systems, and is characterized in that the low-voltage sides of adjacent distribution network transformers are interconnected through an FMSS, and the power can flow bidirectionally through each port of the FMSS, so that the purposes of economical operation of the transformers and load power support are achieved; considering the current situation that the optimal economic operation intervals of transformers with different capacities are different, and taking the optimal economic operation interval constraint of the transformers, the FMSS power operation balance constraint, the interconnection system power balance constraint and the FMSS port capacity constraint as constraint conditions; the maximum adjustable power margin of a master station port and the minimum network loss of the interconnection system are used as target regulation and control, the im
