Multi-port energy hub multi-converter DC voltage/droop control method based on honeycomb active power distribution network

The invention discloses a multi-converter DC voltage/droop control method based on a honeycomb-shaped active power distribution network multi-port energy hub, and the method comprises the steps: a, each multi-port energy hub is internally provided with three DC/AC converters, and a control strategy of a master grid-connected port converter and a control strategy of a slave grid-connected port converter are adopted; b, a plurality of parallel DC/DC converters are arranged in each multi-port energy hub, a control strategy of the DC/DC converters of the energy storage system is adopted, and a corresponding operation area is designed according to the SOC value of the energy storage system; and c, changing parameters of the control strategy of the VSC and the DC/DC converter according to the operation area of the internal energy storage system of the multi-port energy hub. For the multi-port energy hub containing the energy storage system, control strategies of the DC/DC converter and the DC/AC converter in the mu
