PARALLEL LOAD FLOW CALCULATION OF BLOCK BORDERED MODEL

Power system is a large scare network and its equations matrix possesses strong sparsity. Block Bordered Diagonal (BBD) model is widely used in parallel computation of power system. In this paper, after the analysis of various parallel load flow algorithms an asynchronous parallel algorithm, i.e., asynchronous block Newton iterative algorithm, is presented. This algorithm is implemented on PC with multi threads and shows satisfactory convergence.
