Abstract: Static synchronous series compensator (SSSC) is utilised for power flow control and reactive power compensation in transmission lines. In this paper, a new configuration of SSSC based on matrix converter is presented. The proposed SSSC has various advantages over traditional one. It is recognised by bi-directional power flow control capability, elimination of the DC-link, fast dynamic response and simple control system. Using the introduced switching algorithm for ac/ac matrix converter, an approximately sinusoidal series compensation voltage is injected to transmission line with low total harmonic distortion. The optimal parameters of power flow controller are achieved by using cooperative bacterial foraging optimisation. The proposed SSSC is tested at different operating condition by using MATLAB/Simulink software. Results show that the designed control strategy with the new SSSC topology is robust against sudden changes in active and reactive power flow. As well as, it copes significantly with symmetrical and asymmetrical faults conditions. Finally, measurements of system performance validate the proposed technique and emphasise its feasibility.
