An Electromechanical Model of the TotalControl Reference Wind Power Plant

Abstract

An electromechanical model of the TotalControl Reference Wind Power Plant has been built. This is based
on SINTEF's STAS software, for the system dynamics and control of wind power plants. An overview is
given of the theory behind the STAS software, and the architecture of the system model. A wind turbine
control system has been designed, which is well-suited to the STAS model and the upcoming research on
plant control algorithms in the TotalControl project. The STAS model consists of linear/nonlinear equation
pairs, and it is shown how these can be used to obtain Newton-Raphon solutions for operating points, as
well as precise gradients with the complex step approach. A procedure for scaling stochastic atmospheric
turbulence is presented, that greatly accelerates design and optimization studies involving turbulent wind
fields. The detailed electrical design of the TotalControl Reference Wind Power Plant is described, and this
is applied together with the wind turbine module to construct a holistic electromechanical model of the
plant. The dynamics of the plant is characterized in terms of transfer functions
