Title: Economic Dispatch With Security-constrained Rescheduling
Author: Pereira M.V.F.

Abstract: A mathematical framework is described for the solution of the economic dispatch problem with security constraints, which can take into account the system corrective capabilities after an outage has occurred. The solution algorithm is based on mathematical programming decomposition techniques that allow the iterative solution of a 'base-case' economic dispatch and separate contingency analysis with generation rescheduling to eliminate constraint violations. The resulting dispatch has the same security level as the usual security-constrained dispatch, but with lower operating costs. Case studies with the system of Southern Brazil are presented. The extension of the methodology to include other corrective schemes is also discussed. © 1987.
