“…Brucoli et al (1985) presented a sub-optimal control scheme to regulate SVCs; a set of centralised optimal control gains were calculated by minimising a linear quadratic (LQ) index and then suboptimal decentralised control gains were derived from the designed optimal ones by using a minimum norm nearness criterion. La Scala et al (1990Scala et al ( , 1993 also carried out the same sub-optimal LQ control scheme on TCPSs. Chen and Andersson (1995) developed a similar LQ method for TCSC and TCBR but on the basis of different constrained criterion.…”

This paper develops a proportional plus derivative (PD) control scheme for a thyristor controlled series compensator (TCSC) to reinforce power system damping performance. This PD control scheme is aided by the use of genetic algorithms (GAs). The effectiveness of the proposed method is demonstrated through computer simulation using a multi-machine power system associated with a single TCSC. Results show that the proposed PD controller can achieve good damping performance

Static phase shijlers (SPS) have the abilities to optimize power flow and to improve transient stability of power systems. In this paper, improving transient stability of the power system using the static phase shifrer is considered.First, a nonlinear robust model of the power system including SPS is established. Then a Backstepping method is used to construct the storagefinction, and a disturbance attenuation controller in the sense of L2-gain is achieved consequently. The controller reflects the nonlinearity of the system and attenuates disturbances explicitly. Simulations have proved the effectiveness of the nonlinear disturbance attenuation controller.
