Power flow and rotor angle stability studies of HVAC-HVDC power system interconnections using DigSILENT
The backbone of all industrialised nations is the success of the power sector, which involves an efficient, reliable and secure means of power generation, transmission and distribution. Industrial growth and urbanisation have together endlessly stimulated electrical engineers to ensure that the …

Investigation into voltage and angle stability of a hybrid HVAC-HVDC power network
This study investigates the power stability problems of HVDC and VSC-HVDC interactions on their hybrid networks with HV AC link, with the intention of bringing out their weaknesses and strengths. The knowledge of this will assist network planners to be informed on ways of improving the efficiency …

Modeling, control and stability analysis of VSC-HVDC links embedded in a weak multi-machine AC system.
… controllers for enhancing the small-disturbance rotor-angle stability of a weak multi-machine power system with embedded VSC-HVDC links. Three types of linear current controller schemes (proportional-integral, proportional-resonant and Dead-Beat schemes) are investigated and discussed in detail …

Hierarchical Decentralized Control for Enhanced Stability of Large-Scale Power Systems
… enhancement in a unified manner of voltage and rotor angle stability in large-scale power systems subject to large (e.g., short circuits) and small (e.g., small load changes) disturbances. We study system robustness by calculating local stability margins. We derive decentralized control laws …

On-line Dynamic Security Assessment in Power Systems.
… will be less predictable. Consequently, today's stability and security assessment tools, which are generally dependent on extensive off-line studies, may no longer be feasible in their current development state. A core component of an efficient on-line dynamic security assessment is a fast and …
