EVALUATING THE EFFECT OF LOAD GROWTH ON ANNUAL NETWORK LOSSES IN TNEP CONSIDERING BUNDLE LINES USING DCGA

The main task of transmission network expansion planning (TNEP) is minimization of the network expansion and operational costs, and providing required adequacy of lines along the planning horizon while meeting imposed technical and economic constraints. Until now, much research has been presented on the field of static transmission network expansion planning (STNEP). However, in all of them, the effect of load growth on annual network losses in transmission expansion planning has not been investigated. Therefore, in this paper, the STNEP problem is being studied considering the load growth effect on annual network losses by decimal codification genetic algorithm (DCGA). Finally, the proposed idea is tested on an actual transmission network of the Azerbaijan regional electric company, Iran. The results reveal that load growth has important effect on amount of annual network losses and subsequent network configuration. In addition, considering effect of this parameter on the network losses in TNEP is caused the total expansion cost of network (expansion cost of lines and substations) is calculated more exactly.
