Many efforts have been made for optimization of generation and transmission network. The present paper aims at studying 9-busbar and IEEE modified 001-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 removinglines. 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 118 significant; and system miniaturization remarkably reduces the computational costs
