The bus impedance matrix of a $$4$$-bus power system is given by
$$${Z_{bus}} = \left[ {\matrix{
{j0.3435} & {j0.2860} & {j0.2723} & {j0.277} \cr
{j0.2860} & {j0.3408} & {j0.2586} & {j0.2414} \cr
{j0.2723} & {j0.2586} & {j0.2791} & {j0.2209} \cr
{j0.2277} & {j0.2414} & {j0.2209} & {j0.2791} \cr
} } \right]$$$
A branch having an impedance of $$j0.2\Omega $$ is connected between bus $$2$$ and the reference. Then the values of $${Z_{22,new}}$$ and $${Z_{23,new}}$$ of the bus impedance matrix of the modified network are respectively

A power system consists of 2 areas (Area 1 and Area 2) connected by a single tie line (figure). It is required to carry out a load flow study on this system. While entering the network data, the tie-line data (connectivity and parameters) is inadvertently left out. If the load flow program is run with this incomplete data.
