I believe the best you can do from the bus admittance matrix is reconstruct the
series branch parameters (r and x) from the off-diagonal terms and then use
them in (9.1) to get the series losses.
Unfortunately, the line charging injections are aggregated for all lines
connected to a bus (and any other shunts connected to the bus), so I’m not sure
you can disaggregate those. For that matter, series losses are also aggregated
for parallel lines.

Given the voltage phasors at the buses, how can we calculate (or estimate) the
branch series losses and line charging injections using the bus admittance
matrix (not the parameters of the individual branch elements per Equations
