Multivariable Adaptive Hybrid Control Model for Interconnected Power Systems at the Inception of Voltage Collapse
Abstract :
Power systems are one of the largest and most intricate nonlinear systems in the world. Bifurcations phenomena are not rather mundane phenomena in electrical power systems. Bifurcations phenomena is determined to be vital factors at the inception of voltage collapse. In this study, multivariable adaptive hybrid controller behaviors are proposed in order to control bifurcation in electrical power systems. The proposed control system comprises nonlinear controller ineffectiveness. The interaction terms, and then gains are optimally and automatically tuned using expert systems. Robust computational tools for bifurcation analysis have been performed in order to investigation significant multivariable adaptive problems arising in electrical power systems. The multivariable adaptive hybrid controller gives better initial response than invariable controller. The simulation results show that this new method is capable of controlling the system effectively.
