Economic Dispatch Reserve Allocation

In this paper, the economic dispatch problem is reformulated to include a constraint on the maximum average system frequency deviation of a power system following a postulated disturbance. The economic dispatch problem is translated into a well-defined nonlinear mathematical programming problem whose solution is obtained by solving a sequence of linear programming problems. Test results on a 20-node power system to demonstrate the improvement in the post-disturbance maximum average system frequency deviation and the relative trade-off in generation costs are included.
