Abstract

The paper presents a new method for load flow solution for large electric networks. The computation time is reduced by tearing the network into a number of subsystems. Each of the decomposed sub network is a separate load flow problem to be solved. 
The solution of sub networks may be executed in parallel, resulting in a considerable time saying for on line control. The separate solutions are iteratively driven, via a hierarchical coordinator, into the original load TIO solution employing the interaction prediction principle. A theorem to guarantee convergence of the algorithm and illustrative examples are given.
