Abstract

Transmission network expansion planning (TNEP) is such an important issue in power system planning that the proposed structure must have optimal performance besides respecting technical constraints. In this paper, the TNEP problem is formulated considering the worth of network adequacy as well as equipment depreciation by means of the sum of years’ digit method. For this purpose, an economic based definition is presented for the network adequacy and accuracy of the proposed network adequacy model is evaluated by means of the statistical studies besides a multi-objective approach. The developed algorithm takes different electrical constraints such as voltage drops, power flow, N-1 criteria, and all prevalent cost indices into consideration. Moreover, an Artificial Bee Colony (ABC) based algorithm is employed to solve the TNEP. The proposed method is conducted on the Garver’s test system as well as an actual large scale transmission network with about 2,713,300 customers, followed by a discussion on results.
