Cooperative Control of TCSC to Relieve the Stress of Cyber-physical Power System
For power system operators, this work addresses stress relief in cyber-physical power systems, but the method is incremental as it combines existing TCSC control with an approximate Jacobian estimation.
This paper proposes a cooperative control algorithm for Thyristor-Controlled Series Compensation (TCSC) to reduce stress in cyber-physical power systems by adjusting branch impedance and regulating power flow. Simulations on IEEE 24 Bus Systems validate the approach, showing convergence of the stress performance index.
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.
