Summary The paper presents a multi‐year, multi‐objective framework for integrating Renewable Energy Sources (RESs) into the high voltage transmission network of Iran's National Power Grid (INPG). The objective functions in this study are the total cost, including the investment cost and operating cost for the planning horizon, and the system reliability. The first objective function is stated from the economic point of view, while the second objective function is considered as a security index in the expansion planning issue. The main purpose of this paper is to increase the RES penetration into the generation mix of INPG. Since the mentioned 230 to 400‐kV INPG is a large‐scale power system, the problem formulation is investigated in a mixed‐integer programming, and then, the developed multi‐objective problem has been solved using the augmented epsilon‐constraint optimization method. In order to select the executive plan for installation, the fuzzy satisfying decision‐making procedure is adopted in this study.
