Abstract:

 

A new weighted-sum multiobjective approach is investigated for order  reduction based on Routh--Padé approximation, in which the harmony  search algorithm is used to optimize the reduced-order model's parameters.  In this method, apart from minimizing the errors between a set of subsequent  time moments/Markov parameters of the system and those of the model, the  error between the singular values of the reduced-order system and those of  the original system is minimized. The Routh criterion is applied for  specifying the stability conditions. The stability condition is then  considered as a constraint in the optimization problem. To present the  ability of the proposed method, 3 test systems are reduced. The results  obtained show that the proposed approach performs well.
