Disturbances auto-rejection control of TCSC in power systems

Presents a disturbances auto-rejection control (DARC) strategy for control of thyristor controlled series compensation (TCSC) to improve the power system transient stability. This novel nonlinear controller possesses a simple structure and its design does not require system models. DARC performs as an adaptive control scheme with a robust feature in rejecting disturbances. A simulation study undertaken based on nine-machine and forty-one-bus power system shows that DARC can provide satisfactory control performance and improve system stability with a great potential for control of FACTS in power systems
