Influencia de la penetración eólica en la estabilidad de frecuencia y voltaje en el sistema nacional interconectado

Abstract

Due to the continuing trend of replacing power generation based on fossil fuels with renewable and clean energy, this document presents the insertion of wind power can influence the voltage and frequency stability in the interconnected national system. For voltage stability analysis the country was divided in two zones, northern and southern, including dry and rainy scenes in minimum, medium and maximum demand, for which has been made PV, QV curves, sensitivity factors for long-term voltage stability, and for short-term voltage stability. This has been made for three-phase faults in three different lines for representative wind parks in the system, in order to show their behavior. In this project, is going to simulate the contribution of reactive power of each wind park, the voltage at the connection bus, and other variables. The frequency response for an event of connection and disconnection was simulated in a unit of the power generation Daule Peripa, to visualize the behavior with and without wind generation. The comparison between wind generation and thermal generation at the same wind parks insertion buses have been done by PV and QV curves. Also, the frequency response was graphed for wind and thermal generation. Furthermore, this work compares the cost of wind energy and thermal energy generation.
