Aim at the complexity and diversity of power quality in the micro-grid, the generalized proportional-integral controller based on multi-goal optimization is proposed in this paper, which is applied to the comprehensive control device of power quality to realize the optimal compensation aim and the optimal allocation of compensation capacity. The problem that traditional PI control method is unable to track the ac reference signal is solved as well. The simulation model based on PSCAD and physical test platform are put up to demonstrate the effectiveness of the proposed methods. The simulation and physical results show that the all the issue of the micro-grid power qualities are managed by the comprehensive control device of power quality with the proposed methods. The purpose of all the issue of the micro-grid power qualities are managed by a device only.
