Abstract

In power system, utility engineers are often faced with the challenge of reinforcing weak power networks without adding any new infrastructures. This paper analyses the topological structure of a topologically weak network and then institutes a way of reinforcing the network through restructuring. The proposed scheme explores the concept of network structural characteristics of power networks in conjunction with the shortest electrical distance from graph theory. The branch impedances of new sets of candidate transmission lines that could possibly reinforce the existing structurally weak network are determined. The standard IEEE 5-bus and 30-bus test systems are used to illustrate the effectiveness of the proposed scheme. The results obtained show that the proposed approach is generally useful in power system network design, planning and efficient operation.
