Abstract: Considered is the separable non-convex steady state problem for large-scale systems. A three-level hierarchical optimization algorithm is proposed. It converts the original problem into a separable multiobjective optimization problem. The noninfreior frontier is then convexified and the global optimal solution of the original problem is selected from the set of noninferior solutions of multiobjective optimization problem. Theoretical base of the algorithm is established. Simulation shows that the present algorithm is effective.
