A method for real-time online control of three-phase unbalanced load in distribution area was proposed in this paper. The general idea was presented firstly, and then the implementations of online automatic commutation device and control terminal for low-voltage load were described in details. In order to pursue the lowest unbalance radio of three-phase current and the least switching frequency of online automatic commutation device during the commutation process, a multi-objective mathematical model for optimal commutation was established. Then the control strategies for real-time online management can be obtained based on vector-genetic optimization algorithm. The simulation results prove the validity and feasibility of the proposed method.
