Abstract :
Voltage stability is an important aspect in power system planning and operation. In this paper, the applicability of first-order eigenvalue sensitivity for preventive control and planning of reactive power compensator for voltage stability is investigated. First-order eigenvalue sensitivity is used to determine the most suitable generator for rescheduling and to find the best location for shunt reactive power compensation. The change in generation and the amount of shunt compensation required are determined from the sensitivities obtained. Voltage stability depends on load dynamics. Loads are therefore represented by a dynamic model. Analysis is carried out on the 17-generator, 162-bus system and the results are presented.
