Stability Analysis For Networked Power Systems With Lfc And Event-Triggered Communication

This paper is dedicated to investigate the stability problem of multi-area networked power systems with load frequency control (LFC) and event triggered communication. To save limited network resources and improve the data transmission efficiency, an ACE-dependent time-delay model is constructed to describe the multi-area networked power system via event-triggering mechanism. By utilizing the Lyapunov theory, a delay-dependent stability criterion for networked power systems is presented in terms of linear matrix inequality. Finally, a three-area power system based on MATLAB is provided to show the superiority and effectiveness of the proposed method.
