Effect of Demand Response Programs on Power System Security in Emergencies Considering Passive Defense Criteria

Providing power supplies for vital military centers in critical conditions is one of the important criteria of passive defense. Increasing power system reliability، resolving energy loss in peak hours and transmission lines congestion are the main purposes of Demand Response Programs (DRPs) development. DRPs have been designed to consider the consumers participation in power system operation. In this paper، both the spinning reserve and the demand side reserve، which is modeled as Emergency Demand Response Program (EDRP) and Time of Use (TOU) program، are taken into account as the operating reserve services. The two-stage stochastic Security Constrained Unit Commitment (SCUC) has been utilized to consider emergencies. The proposed model is applied to a sample power system which has some special costumers (such as militaries، basic industries، administrative and home). The results show that the DRPs have a great effect on power system security، increasing the whole system and its special costumers reliability.
