ABSTRACT
Distribution power flow is the foundation of work analysis. After deeply analyzing traditional power flow algorithms,this thesis has proposed a fast load flow algorithm based on algorithm including second order breaking Jacobian matrix into four sub—Jaconbian matrixes whose size is smaller than Jacobian matrix,the algorithm simplifies the calculation of the inverse matrix of Jacobian matrix,which can be applied to plex with the former algorithm,the improved algorithm has faster run times and beRer stability.
A distribution power flow software based on the improved algorithm has been developed with Fortran programming language on puteL some functions,such as power flow calculation work loss has been realized.
This improved algorithm has been tested on the 27一bus and 33一bus systems. The results show that it has better convergence and stability properties,special superiority on the solution of the distribution systems with loops,and can solve
problem of work.
