Smoothness of voltage stability surface with generator reactive power limit encountered

2008 Third International Conference on Electric Utility Deregulation and Restructuring and Power Technologies, 2008
When constraints of generators are encountered, a stable power system can become unstable immediately and voltage collapse may occur. One of these constraints considered in the paper is the reactive power limit of generators. Based on an effective control strategy, the smoothness of the transfer limit surface of voltage stability is studied by ...

Effect of generator reactive power limit on proximity to voltage instability of multibus power system

2017 12th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2017
Voltage stability is dominant in heavily loaded systems with large disturbances. This is typically the case in the deregulated environment wherein the transmission systems are operating under more stressed condition. This is due to increased transaction level associated with open access. Abnormal voltage instability has occurred in several countries in

Incorporating generator reactive power limits into constrained-genetic-algorithm load flow

APSCOM-97. International Conference on Advances in Power System Control, Operation and Management, 1997
This paper develops a method to deal with the generator reactive power limits in a genetic algorithm-based environment. In this method, the limits are treated as inequality constraints. The developed method for treating the reactive power limits and the technique usually adopted in Newton-Raphson load flow are compared.

Voltage Stability Limit of Electric Power Systems With Generator Reactive Power Constraints Considered

IEEE Transactions on Power Systems, 2005
This paper investigates the smoothness of the transfer limit surface, or the loadability surface, of power systems. The reactive power output constraints of generators are taken into consideration. A new methodology employed for the investigation is based on characterizing each maximum loading point by the state of the generators (PV or PQ).

Generator reactive power limits and voltage stability

Fourth International Conference on Power System Control and Management, 1996
Generator reactive power limit is a key factor in voltage instability. When the field or armature current limit becomes active, the generator reactive power limit becomes voltage dependent. These operational limits and the shifting between field limit and armature limit, are fully investigated.
