To perfect the application of the fault current limiter in grid and improve the use efficiency, an optimal configuration method of fault current limiter based on multi-objective decision is proposed. Firstly, use rate of current change to select alternative branches, then taking the cost and current-limiting effect of fault current limiter as the targets, considering installation location, quantity of fault current limiter comprehensively, using α-method to determine the weight coefficient, establish multi-objective optimization model, and use immune algorithm to obtain the optimal scheme of branch installation. Next, by comparing the configuration of fault current limiter in the bus connection, the best configuration scheme is obtained. Finally, this method is verified by analyzing the IEEE39 node standard network.
