    Abstract: Many efforts have been made for optimization
of generation and transmission network. The present
paper aims at studying 9-busbar and IEEE modified
118-busbar systems for the sake of miniaturization of
power system model. Though network reduction results
into a simple but precise model, lack of proper current
limiting can constrain its applications. This problem can
be solved through reformation of transmission network
including split bus and removing lines. To this end,
MATLAB software was used. The obtained results
revealed that using modified busbar systems for the sake
of optimization of power systems is to 80% significant;
and system miniaturization remarkably reduces the
computational costs.
