【Abstract】 Considered is the nonseparable steady state problem for largescale systems, where the overall objective function is not of an additive form with respect to subsystems. A threelevel hierarchical optimization algorithm is proposed. It first converts the nonseparable problem into separable multiobjective optimization problem. The optimal solution of the original problem is then selected from the set of noninferior solutions of multiobjective optimization problem. Theoretical base of the algorithm is established. Simulation shows that the algorithm is effective.更多还原
