On a Wind Farm Aggregate Model Based on the Output Rescaling of a Single Turbine Model
In transmission and distribution grids with a large share of renewable and distributed resources, the potential instabilities (and possible control actions) related to large power fluctuations can be investigated by means of simulation models. In this scenario, suitable methods of aggregation have to be considered to lower the computational cost of simulations. An aggregate model of a complex system is a reduced model which allows avoiding the repetition of a component model the number of times that such a component is present in the system. This paper reviews a wind farm aggregate model especially tailored to reproduce the power fluctuations due to wind turbulence (up to about 10 min). The structure of the model is justified by means of statistical considerations.
