Hello everyone, I have some problem understanding the direction of the reactive power flow. How do I calculate the flow of reactive power through a single line (i.e. for branch 1 here)? Also how to calculate the flow when signs for both of to and from buses are negative (i.e. branch 3)?
I know it has something to do with line susceptance, but could not exactly figure it out. Should not the absolute value of reactive power flow from Bus 1 to 4, and from Bus 4 to 1 should be the same? I will highly appreciate some clarification regarding this.
