Flexible programming approach to security-constrained economic dispatch

An approach to the solution of security-constrained economic dispatch is proposed. A flexible programming technique is used which permits uncertainties in the load-demand profile to be taken into consideration in the determination of the optimal solution to economic dispatch under line-flow constraints. A linear-programming formulation of the security-constrained dispatch is the basis of this approach which provides not only the optimal dispatch policy but also the optimal amount of generation reserve needed to accommodate uncertainties in the load.
