Resumo: | The wind generation has stood out among the alternative sources and has experienced a high rate of penetration through the years. Thus, the electrical connection of wind power generation must be analyzed in detail to avoid or minimize the problems inherent this type of source can cause in electric power systems (SEP) and thereby preserve the voltage quality indicators and reliability. This paper deal about the integration of wind farms in SEP, equipped with squirrel-cage induction generator based fixed speed wind turbines (AVV-SCIG) and doublyfed induction generator based variable speed wind turbines (AVV-DFIG). The limits of integration of wind energy generation, i.e., the amount of power that the wind farm can provide the point-of-common-connection (PCC) while complying with certain interconnections requirements, are obtained considering static and transient aspects of the connection of wind farms. The topology adopted to represent, in a simplified way, the local characteristics of the connection between the wind farm and the SEP, as well as characterize the integration of wind generation from the parameters of the PCC, is the single machine infinite-bus system (MBI). Throughout the text also are presents the models used to represent the wind turbine and wind farm in studies of power systems, the main criteria specified to connection of this type of source in SEP and the main issues dealing with the problem of integration of generation wind. The analyzes aim to assess how the wind energy generation is impacted by technical criteria that consider static and transient aspects of the connection of wind farms, the technology used in energy conversion, the control strategy/operation and the characteristics of PCC. The results obtained allow to define which the stricts conditions for the integration of wind energy generation. For these analyzes are considered the criteria of the maximum allowable voltage variation at the connection point of the wind farm, the power range for the maximum transferable power to the electrical system and the fault ride through capability. |
