Abstract
This paper considers the optimization of line loss calculation and the improvement of the rapidity of power flow analysis. A novel splitting strategy, say, decoupling the topology associated with the power gird into the main network containing the power branch and the subnet-based segmentation, is proposed to reduce the iterative matrix dimension, which makes it possible to calculate the subnet and the main net with the tools of Newton-Raphson method and the fast flow algorithm separately. The feasibility and effectiveness of the proposed scheme are proven by simulation results of the IEEE-30 Bus system.
