A Design of Diakoptic Method based on Sparse Vector Method for the Power System

스파스 벡터 기법을 이용한 전력계통 분할 알고리즘의 개발

Diakoptic method applied to analyze large power system, always require the efficient tearing algorithm. But conventional tearing methods is not suitable to apply practical power system. This paper presents new tearing algorithm based on factorization path concept of sparse vector method, and applied MPRLD, a kind of optimal ordering algorithm, in ordering step to improve the efficiency of tearing algorithm. Test result of model systems shows that new proposed method in this paper is enable to tear power systems not to be teared by heuristic cluster method, reduces computing time and memory size.
