| Abstract | ||
| A large scale optimum dispatch ,using the DFP(Davidon-Flitcher-Powell) procedure ,is presented for system in both normal as well as emergency states. Optimum rescheduling of control variables for system in amulet –contingency state includes minimization of the operating cost. A Satisfaction is made for system constraints for all selected line-outages .single line outage is also dispatched . Results obtained for the 5-bus and 30-bus test system indicate that single as well as multi-contingency dispatch converge after four DFP-iterations. Compared with optimum operating cost of system in its healthy (normal) condition , results obtained show an increase in the fuel cost for both the single and multi-contingency states . However, optimum cost for system operation during some of the single line-outages selected, is lower than that of a multicontingency operation . This encourages the dispatcher to reschedule control operation . This encourages the dispatcher to reschedule control variables during each contingency. However, if security is preferred on cost-minimization the dispatcher will depend on the results of a multicontingency optimum schedule , and no reschedule is required for control variables during emergency. | ||
