When higher order Taylor series is expanded, it is necessary only to conduct fast forward and backward iteration based on triangle decomposing of .

Considering the features of the storage way of the data of GIS, it improves the technology of node- ordering of traditional Backward/forward and builds the special node data structure.

The algorithm avoids irrelevant computation requirement in solving large sparse network equations by exploiting sparse vector method, partial matrix refactorization and fast forward/fast backward techniques.

Study on calculating theoretically line loss using forward and backward substitution method;

On the basis of analyzing the current techniques for power flow calculations of distribution network,by improving the traditional forward and backward substitution method,a calculation applied for the reliable distribution network is presented,which has practicability.

This paper discusses the latent parallel characteristic of the forward and backward substitution method in tidal current computation.

Calculation of multi-source distribution network loss based on back/forward sweep method and measurement resource

The simplified condition of the back/forward sweep method and the realization of the improved algorithm using computer are given.

The characteristics and differences of back/forward sweep method and Newton method are compared and analyzed,and a modified back/forward sweep method is proposed based on the conventional back/forward sweep method, in which the correction equation of node voltage in the back sweep process is just simply replaced by a new equation.
