Abstract

Some years ago, electrical systems have experienced a rapid growth of wind energy, due to the need to replace polluting energy sources, a situation that has led to modifications in the requirements for the operation of a power system, with the aim that wind power plants do not affect the stability of the system. The present work seeks to study the dynamics of doubly fed induction generators (DFIGs), focusing on their voltage response to disturbances and their compliance with the regulations established for their connection to a power system. These codes are used in the system called ""grid code"". Being the most representative of the German and Irish codes; in Ecuador, there is only a regulation that indicates certain parameters for its connection or disconnection. To achieve this, a wind turbine has been modeled and time domain simulations of the DFIG wind generator are obtained in PowerFactory for two demand scenarios. The simulation results are evaluated to determine whether the generators meet the voltage curve requirements outlined by the selected grid codes. The work contributes to the analysis of the voltage variable within the grid codes for the integration of wind energy in systems with synchronous generation, through the development of analysis in a test system, where it is observed that adequate results were achieved in the voltage variable for the analyzed scenarios.
