In the distribution system with multi DFACTS devices, controllers are separately designed aiming at different functions, that means the controllers are isolated even contradictory. In allusion to the problem that the separately designed DFACTS controllers exist interactions, the paper turns the coordination of the DFACTS controller into multiple target optimization problems, takes the single-load infinite-bus distribution system with DSVC and DSTATCOM as the research object, using the (Non-Dominated Sorting Genetic Algorithm-II, NSGA-II) for DFACTS controller parameters optimization. And the simulation results show the effectiveness of the algorithm.
