AbstractThis paper discusses the inclusion of wind generation in load-frequency control (LFC) of a hydro-wind power system through the control technique known as virtual synchronous generator (VSG), which makes static power converters, which connect the wind farms to the grid, emulate the behavior of a real synchronous generator. In addition, wind generation is considered to operate in unloaded mode, having generation reserve to deal with system load disturbances. It was found that with the participation of wind generation in the LFC, there is a significant reduction in the frequency deviation and in the inverse response of the hydraulic plant, proving the importance of the participation of wind plants in the LFC.
