The requirement of the probabilistic approach on electric power systems is increasing on the electricity power market with various demanding of electricity power consumers. Moreover the necessity of the reliability evaluation at demand points get higher. To evaluate the reliabilities at demand points the effective load duration curve on the composite power system level (called CMELDC) was developed[1]. As the effective load duration curve plays an important role in probabilistic production cost simulation and reliability evaluation for power system planning, the CMELDC give us useful information to solve nodal probabilistic problems[2]. Two elements are required to construct the CMELDC. The first of it is the probabilistic load model. And the other is the probability of load curtailment model. This paper uses the probabilistic arrival power concept to evaluate reliability at load points. And effect of FACTS devices are presented on the probabilistic reliability.
