Alternating current and direct current flexible interconnection topological structure of multiple power distribution areas

The invention discloses a multi-power distribution area AC/DC flexible interconnection topological structure, which comprises a power quality control unit, the power quality control unit comprises a transformer, the transformer comprises a voltage transformation module and a coupling module, the voltage transformation module is connected with the coupling module and is used for realizing continuous non-stage-difference adjustment of voltage amplitude and phase angle, and the coupling module is connected with the power quality control unit. And an external AC interface is formed. According to the topological structure disclosed by the invention, interconnection and intercommunication of a plurality of power distribution areas in different forms of alternating current or direct current are realized, distributed photovoltaic consumption across the areas and space transfer of loads are realized, and the aim of flexible capacity mutual aid between the power distribution areas is achieved. Meanwhile, the topology h
