  This paper addresses the cooperative control problem of Thyristor-Controlled
Series Compensation (TCSC) to eliminate the stress of cyber-physical power
system. The cyber-physical power system is composed of power network,
protection and control center and communication network. A cooperative control
algorithm of TCSC is developed to adjust the branch impedance and regulate the
power flow. To reduce computation burdens, an approximate method is adopted to
estimate the Jacobian matrix for the generation of 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 proposed cooperative control algorithm is
implemented. Finally, numerical simulations are carried out to validate the
cooperative control approach on IEEE 24 Bus Systems in uncertain environments.
