In this paper, security constrained unit commitment (SCUC) is employed for simultaneous clearing of energy and reserve markets. Spinning reserve of generation units and interruptible loads (IL) are assumed as system operating reserves. In the proposed method, the unit commitment program is done with considering the wind power uncertainty. So, modeling the wind uncertainty has been done by a two-stage stochastic programming. Also, the economic evaluation of wind power uncertainty is discussed and the impacts of IL and wind farm locations have been studied on the system reliability. Expected energy not supplied (EENS) is considered as criterion for undesirable load shedding of power system. Finally, the proposed model is applied to the IEEE reliability test system (IEEE-RTS) to demonstrate its effectiveness.
