Abstract: This article presents the coordinated control of PI type PSS and MISO newly proposed damping controller using SSSC-based PI type lead lag controller for transient stability analysis. The improved grasshopper optimisation algorithm (GOA) is employed in the coordinated controller design problem to find out the optimal controller parameters of SMIB and multi-machine bus power system. A PI type PSS with proposed SSSC controller is analysed to show that the IGOA has satisfactory performance for optimisation problems compared with GOA, DE, PSO techniques. The anticipated design approach of dynamic simulation results is analysed to explain the effectiveness and robustness of the power system. It is verified that a coordinated control of PI type PSS with SSSC-based PI type MISO controller is superior damping performance as compared with individual remote speed deviation and line active power input signal-based PI type PSS with PI type SSSC controller in single and multi-machine power system.

Keywords: transient stability; improved grasshopper optimisation algorithm; IGOA; static synchronous series compensator; PI type MISO controller; PI type PSS; multi machine power system; MMPS.
