- Abstract
To conduct power system simulations with high shares of wind energy, standard wind turbinemodels, which are aimed to be generic rms models for a wide range of windturbine types, have been developed. As a common practice of rms simulations, thepower electronic interface of wind turbines is assumed to be ideallysynchronised, i.e. grid synchronisation (e.g. phase locked loop(PLL)) is not included in simplified wind turbine models. Aswill be shown in this study, this practice causes simulation convergenceproblems during severe voltage dips and when the loss of synchronism occurs. Inorder to provide the simulation convergence without adding complexity to thegeneric models, a first‐order filtering approach is proposed as a phase anglecalculation algorithm in the grid synchronisation of the rms type‐4 wind turbinemodels. The proposed approach provides robustness for the simulation oflarge‐scale power systems with high shares of wind energy.
