This study proposes a novel modified grey-wolf optimization algorithm (MGWOA) to enhance power system stability. The stabilizer and static synchronous series compensator (SSSC) are used as damping controllers. Additionally, fractional-order PID (FOPID) controller is handle the nonlinearities thus achieve better performance. control parameters tuned using proposed MGWOA method which has been ver...

The FACTS (Flexible AC Transmission Systems) devices have great use in the Electric Power System (EPS) for dynamic control of active and reactive powers system. This work deals with a comparative analysis between effects caused distance protection transmission lines (TLs) by two these devices: STATCOM (Static Synchronous Compensator) SSSC Series Compensator). objective is to verify how connecti...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...
