The mathematical models of FACTS devices suitable for optimal power flow computation are established accordingto the principle of UPFC, TCPAR and TCSC respectively so that initial values and limits of their state variables are easilydetermined. Furthermore, the direct nonlinear primal--dual path following algorithm to solve optimal power flow modelincorporating the above FACTS devices is presented, and the effect of branch power flow control on this algorithm is sttldied.The optimization results of IEEE--30 and IEEE--118 bus systems show that the proposed algorithm has strong ability to dealwith the inequality constraints and branch power setting control, while its convergence is affected by the number andinstallation location of FACTS devices.
