A model to incorporate Demand Response Programs in Security Constrained Unit Commitment

The ISO implements Security Constraint Unit Commitment (SCUC) for clearing of day-ahead market. In this paper, SCUC is also used for simultaneous clearing of energy and reserve market. Spinning reserve and of generating units and Demand Response Programs (DRPs) are considered as system operating reserves in the proposed model. A Mixed Integer Programming model is proposed for power system modeling along with DRPs. The proposed model is applied to the IEEE RTS to demonstrate its effectiveness. The results show that the use of DRPs´ reserve, reduce the system operation costs and have high impact in reliability improvement and reduction in market clearing price in critical or peak hours.
