This paper proposes a new approach to the Security Constrained Economic Dispatch based on a nonlinear version of the Dantzig-Wolfe decomposition principle. The dispatch problem is formulated using truly nonlinear unit cost functions and a new, detailed representation of reserve curves. The solutions obtained by the method have the equal {lambda} property. The proposed decomposition scheme is more efficient as the number of generating units in the problem is increased. Numerical results obtained on three test cases are presented.
