Resumen:

This paper addresses the study of the dynamic sensitivities of bus voltage magnitudes with respect to changes in the value of the system's frequency. Frequency emulation of wind energy generators embedded in the power system is considered in the analysis. A dynamic model of a direct-drive wind generation system with a permanent magnet synchronous generator is implemented and integrated along with the dynamic models of traditional synchronous generators and their controls in a MATLAB-based digital program capable of performing large scale power system dynamic simulations. Based on this modeling and implementation, a numerical index is proposed to assess the bus voltage dynamic sensitivity to frequency changes caused by active power load-generation imbalances and emulated inertia response. Lastly, the IEEE 30-bus benchmark system is employed to show the usefulness of the proposed index. © 2016 IEEE.
