Stability Analysis of Cyber-physical System Under Transmission Delay

With the intimate integration of power grids and cyber networks, limited bandwidth packet delay have a rapidly expanding negative impact on system performance. The presented multi-area interconnected consists four areas, each including thermal hydro-generation plants. This paper investigates stability analysis problem for cyber-physical systems with round-robin communication protocol under mixed cyberattacks load changes. objective is to stabilize (MAIPS) using static feedback controller while minimizing defined performance function. Then, MAIPS characterized when subjected transmission considering predetermined limits duration frequency delay. Our findings indicate that time delays can influence choosing an appropriate sampling interval necessary ensure system. Finally, illustrative example three areas several scenarios verify effectiveness proposed method.
