Abstract

The problems of robust overlapping decentralized control for a class of multi-area longitudinal power systems are discussed in this paper. Based on the special overlapping decomposition, a new control method is presented by means of linear matrix inequality (LMI) approach of organically-structured control (OSC). The proposed method is applied to AGC of a four-area longitudinal power system, and the simulation results show that the performances of the controllers designed by proposed method are better than the one by OSC directly. The conclusion is obtained that considering properly the overlapping in systems can improve the control performances.
