Research of hierarchical parallel computation method on theoretical linear loss of distribution grid by graph calculation
With the expansion of scale of distribution network,the low efficiency in in the field of theoretical line loss calculation is highlighted.Based on the theoretical line loss analysis graph model of distribution network,in this paper,a hierarchical parallel calculation method of theoretical line loss is present.The parallel graph calculation method adopts the global synchronous parallel computing model(BSP),which can effectively reduce the power flow calculation time of large distribution networks.Meanwhile,the analysis efficiency of theoretical line loss is improved and the key points of network loss are found quickly and accurately by using the subgraph of sub-feeder to push forward and forward the current calculation.Finally,the validity of the proposed model and algorithm is verified on IEEE123 node model.
