The multi terminal flexible multi state switch in the micro distribution network has the characteristics of flexible multi terminal polymorphic switching,which causes uncertainty and randomness in load and is prone to load imbalance.To this end,a double-layer nested load balancing control system is designed.Design a multi-state switch load main control subsystem module,which controls the micro processing unit of the switch load and receives external commands.By controlling the multi terminal communication interface through load,multi source data transmission through multi terminal access channels is achieved.Construct a two-layer nested weighted minimum objective function for the supply area layer and feeder layer,fully considering the constraint objective function of equivalent losses at both ends of the switch,to avoid losses affecting the system control efficiency.Design a dual layer load dynamic distribution scheme to achieve balanced switching load.According to the simulation results of the system application,the three-dimensional coordinates of the control core of the system are(2,6,200),which can achieve relatively ideal control objectives.
