A methodology for parameter estimation of equivalent wind power plant

A methodology for parameter estimation of equivalent wind power plant is proposed in this paper. The parameter algorithm is formulated as an optimization problem which miminize the output between the real system and the mathematical model. The parameters are updated using Newton-Raphson method which depends on the information of trajectory sensitivity functions. A generic equivalent of wind power plant was used as a structure of the model, which is valid for Double-Fed Induction Generator (DFIG) and full Converter Based Wind Turbine. In addition, the procedure to obtain of the trajectory sensitivity functions of the model is presented in this paper. A discussion of the estimated results is also analysed. In general, the convergence happened in a few seconds for most of the cases studied.
