For this reason, an ap proach using fast decoupling method to process PV nodes is proposed. In the proposed approach, traditional Gaussian algorithm is used to process PQ nodes and the PQ part of work is eliminated by Gaussian elimination method, thus w ork consisting of PV nodes and a balance bus is obtained, and then the work is
