Abstract:
The article presents the load frequency control of an interconnected two-area non-reheated thermal (TANRT) power system in consideration of its inherent nonlinearity present in speed regulation mechanism as governor deadband (GDB) and generation rate constraint (GRC) found in turbine has been studied via utilizing a robust fractional order controller. The community conducts of Salpidae exist in the subterranean sea is the motive behind the newly introduced optimization algorithm known as salp swarm algorithm (SSA), which has been used to obtain the optimal controller parameters. In this work, exclusive simulation studies were performed to establish that SSA-optimized fractional-order controller provides noteworthy enhancement in the dynamic performance of the system with simultaneous presence of inherent nonlinearities, i.e., GRC and GDB under large parametric variations in contrast with GA optimized controllers.
