Determination of construction priority of transmission lines based on probabilistic reliability evaluation

This paper proposes a method for determining the construction priority of transmission lines based on probabilistic reliability evaluation. This method suggests the priority for constructing lines from new transmission lines set of optimal solution obtained by the optimal transmission expansion planning. In this study, the optimality is solved by integer programming using branch and bound method, which utilizes a network flow approach and the maximum flow-minimum cut set theorem to minimize investment budget of transmission line construction and subject to deterministic criterion using a program Cmexp.For. The timing priority of new line construction is determined on the comparison of probabilistic reliability indices of each new system using TRELSS 6.2 program. The proposed method has been tested on IEEE-MRTS.
