Key factors affecting voltage oscillations of distribution networks with distributed generation and induction motor loads
An oscillatory mode (2-10Hz) called critical voltage mode is reported. This mode is sensitive to variations in induction motor parameters and changes in load demands. A bifurcation study is carried out to determine the dynamic loadability limit of the system. This study indicates the importance of understanding oscillations for secure operation of distributed generator integrated systems.
