The Modified Shuffled Frog Leaping (MSFL) algorithm is considered as a multi objective optimization technique to power system in this paper. Since the energy losses because of wakes can significantly decrease the energy production and lead to fluctuations in the output power of a wind farm it is desired to determine optimal positions for installing multiple wind turbines. The proposed technique minimizes simultaneously the fuel cost and emission of thermal units by changing location and varying sizes of wind farm. The features and the advantages of MSFL algorithm, such as escaping from local optima traps, global optimization, good robustness, simple mechanism and fast convergence, would make MSFL method as a promising optimization approach. In this paper the wind farm in form of doubly fed induction generator penetrating is formulated into a power system.
