摘要： This paper addresses the cooperative control problem of Thyristor-Controlled Series Compensation (TCSC) for eliminating the stress of cyber-physical power system. Specifically, the cyber-physical power system is composed of power transmission network, flexible alternate current transmission systems (FACTS) devices, phasor measurement unit (PMU), and protection and control center. A cooperative control algorithm of TCSC is developed to adjust the branch impedance and redistribute the power flow for the stress relief. To reduce computation burdens, an approximate method is adopted to estimate the Jacobian matrix for producing the TCSC control signals. In addition, a performance index is introduced to quantify the stress level of power system. Theoretical analysis is conducted to guarantee the convergence of performance index when the cooperative control algorithm is implemented in the uncertain environment. Finally, numerical simulations are carried out to validate the cooperative control approach on IEEE 24 Bus Systems with the advantages over the PID control.
