Performance of Steady-State Voltage Stability Analysis in MATLAB Environment
Abstract
In recent years, electric power systems havebeen often operated close to their working limits due to
increased power consumptions and installation of
renewable power sources. This situation poses a serious
threat to stable network operation and control. Therefore,
voltage stability is currently one of key topics worldwide for
preventing related black-out scenarios. In this paper,
modelling and simulations of steady-state stability problems
in MATLAB environment are performed using authordeveloped
computational tool implementing both
conventional and more advanced numerical approaches.
Their performance is compared with the Simulink-based
library Power System Analysis Toolbox (PSAT) in terms of
solution accuracy, CPU time and possible limitations.
