Ybus Construction: Parallel Branch Modelling for Power Flow

2021-07-16 Thread Liang Chen
Dear all, I have a question regarding the construction of the admittance matrix (Equations 3.11-3.13 in the documentation, Modelling > Network Equations). I noticed that there are cases in which there are more than one branch from bus i to bus j, and cases where there are branches (i,j) and (j,

It is perfectly fine to replace parallel branches with a single equivalent branch. If done properly, it will result in an identical power flow solution. Ray On Jul 16, 2021, at 1:22 PM, Liang Chen mailto:liangjie.c...@mail.utoronto.ca>> wrote: Dear all, I have a question regarding the con
