Study of Active Power Load-flow Algorithm

A newly active power load-flow algorithm is proposed, which perfectly decoupled active and reactive power under the same assumed condition of FDLF. In the intermediate process, algorithm of active and reactive power does not need mutual iteration. Through analysis of examples, the error is within the permitted scope of project, and the algorithm has a good convergence especially when the ratio of R/X is very large. The algorithm is especially suitable for on-line load-flow analysis, and is also used as reserve algorithm of FDLF.
