With the large-scale integration of intermittent new energy and diverse flexible loads

the imbalance between feeders has intensified. To achieve feeder load balancing and stabilize DC voltage

an event-triggered dynamic consistency algorithm based feeder load balancing control strategy is proposed. First

the event-triggered dynamic consistency algorithm is designed to calculate the relevant state variables

which avoids centralized information processing. Second

a power calculation module and a power update module for feeder load balancing control are designed

enabling distributed feeder load balancing. Then

the droop characteristic curve and power reference value are improved based on voltage droop control to achieve zero-error tracking of the DC voltage. Finally

a four-terminal MMC flexible interconnected distribution network is developed on the PSCAD/EMTDC platform to verify the effectiveness of the proposed control strategy. Simulation results show that the proposed control strategy can rapidly balance the feeder loads

enhance the reliability of DC voltage control

and reduce system communication volume.
