| Abstract: | The multifrontal algorithm(MA)and conventional direct sparse factorization method are described and compared.Upon applying MA to load flow calculation of IEEE 118 and IEEE 300 node systems as well as the transient stability analysis and computation of IEEE 145 node system,it is concluded that the load flow calculation and transient stability analysis using MA has higher efficiency,more obvious speed-up ratio and larger application scope than conventional direct sparse factorization technique.Furthermore,due... |
