Analysis of dynamic stability of power system using thyristor controlled phase shifter
ABSTRACT In this paper, the application of thyristor controlled phase shifter (TCPS) in damping power system oscillation is investigated. Analysis is carried out considering TCPS equipped with conventional lead-lag controller and with proportional-integral-derivative (P-I-D) controller. Parameters and gain settings of the TCPS controller are optimized using genetic algorithm (GA). Dynamic performances considering conventional phase lead-lag power system stabilizer (CPSS) and TCPS are compared. Analysis reveals that TCPS equipped with P-I-D controller improves the dynamic performances significantly as compared to that of conventional power system stabilizer.

ABSTRACT: This paper extends the highly versatile method, known as the Plug-in Modeling Technique(PMT) to several FACTS devices, such as TCSC, SVC and TCPS, and a new type of generator, i.e. DFIG type of wind turbine generator. A case study to illustrated the FACTS and DFIG type of wind turbine is demonstrated.Power Electronics for Distributed Generation Systems (PEDG), 2010 2nd IEEE International Symposium on; 07/2010

ABSTRACT: In this paper, to control the power flow and improve the dynamic characteristic of power system, TCPS is applied in power grid. The structure of TCPS and two types of models are introduced and derived. The proposed models are demonstrated by a test system.Innovative Smart Grid Technologies - Asia (ISGT Asia), 2012 IEEE; 01/2012
