Transmission network expansion planning (TNEP) is an important part of the electric power system development. In this paper, the TNEP is investigated as a new framework considering actual worth of network adequacy. To do so, a new economic based definition is introduced for network adequacy and statistical studies are developed to calculate the actual worth of network adequacy via proposed formulation. Next, the TNEP is investigated as an optimization problem, with two objectives, using Artificial Bee Colony algorithm. Moreover, new heuristic approaches are presented to enhance the optimization process. Detailed numerical studies and comparisons presented in the paper show that the proposed approach could improve the quality of problem solutions and can be used as a new framework for TNEP within actual networks.
