SOLVING POWER FLOW EQUATIONSWITH INEXACT NEWTON METHODSPRECONDITIONED BY INCOMPLETE LU FACTORIZATION WITH PARTIALLY FILL-IN

Cai Dayong,Chen Yurong Tsinghua University,Beijing10 0 0 84 ,China  
The problem s of power flow calculation with inexact Newton methods are discussed in detail.It is suggested that the sparse incomplete L U factorization IL U with partial fill- in is a better- preconditioned m ethod for solving power flow equations faster.Then,a serial im plem entation of the new m ethod is performed on the IEEE 118- bus system,and the numerical results show that the number of floating- point operation count of the new method is significantly less than that of the no fill- in case.
