%0 Journal Article %T Effect of Slack Bus Selection in Load Flow Solution and the Total Generation Cost %A Jumana A. Alshawawreh %A Atef S. Al-Mashaqbeh %J International Journal of Electrical, Electronics and Computer Systems (IJEECS) %D 2013 %I International Journal of Electrical, Electronics and Computer Systems %X The effect of slack bus selection in power system is examined in this paper, where the results show an extreme variation in the transmission line losses and the total generation cost based on the slack bus selection. The total generation cost was decreased by approximate 0.5 million dollar per a year without using any minimizing techniques. the generation cost and the total power losses are also affected by the slack bus voltage, where the combination between the slack bus and its voltage should be considered in the optimal power flow problem. %U http://www.ijeecs.org/archive/02.January_2013_IJEECS_p21345.pdf?attredirects=0
