In this paper a new approach on hybrid generation and transmission expansion planning in power systems is introduced. The proposed approach presents a multi-objective planning method which simultaneously minimizes total cost of planning (including non-uniform fuel cost and investment cost of new generation units and transmission lines), total NO and SO2 emission and a security index called ELNS (Expected Load Not Served). The DC power flow is used to model the transmission flow constraint. Furthermore, fuel supply limitation has been included for thermal units. More than one candidate line with different reactances and capacities in each corridor has been used which makes the model more practical in transmission expansion sector. This work is an effort to implement the augmented epsilon-constraint method for generating the Pareto optimal solutions in the hybrid expansion problem. In order to select the best solution among Pareto solutions, Analytic Hierarchy Process (AHP) method has been used. To prove the efficiency of the proposed method, numerical simulation results on the modified Carver's 6-bus system and 24-bus IEEE reliability test system are presented. The results show good performance of the proposed method.
