چکیده :

In this paper, a network stability analysis algorithm is proposed for the uncertain interconnected systems. To reduce the complexity of analysis, compositional certification strategy is adopted, i.e., instead of studying the characteristics of the whole network, the property of subsystems is assessed. The proposed method firstly analyzes a dissipative property of subsystems of the interconnected system. Then, by taking the uncertainty of interconnections into account, a compositional stability criterion is given for stability analysis of the network. Compared with some previous investigations, the presented algorithm has less computation burden, which facilitates the application to large-scale interconnected power systems. Numerical analysis confirms the proposed method can assess the stability of an IEEE 14-bus test system, in the presence of uncertainties.
