The static synchronous series compensator (SSSC) is one of the series flexible AC transmission system (FACTS) devices that can be used in power flow control and reactive compensation in transmission lines. In this paper, a new configuration of SSSC based on a matrix converter is presented. The proposed SSSC has some advantages such as elimination of the DC link, bidirectional power flow control capability, fast dynamic response, and simple control system. By presenting a switching algorithm for the AC-AC matrix converter, an almost sinusoidal series compensation voltage is injected to the transmission line with low total harmonic distortion. In this paper, a modified particle swarm optimization (PSO) algorithm is used to obtain the optimal parameters of a power flow controller. The modified PSO algorithm is simulated annealing-PSO. Application of the proposed SSSC in different operating points is simulated by MATLAB/Simulink software. Simulation results verify that the designed control system enables the proposed SSSC topology with independent control of active and reactive power flow in transmission lines. Presented simulation results confirm the validity and effectiveness of the suggested SSSC in power flow controlling system.
