“…It enables programming variables for various types of winds (blasts, turbulences) as an input and regulates the turbine power by changing the attack angle of the blades; however, it does not take into account the wake effect. The model, firstly presented in [45], has been extended and modified. Virtual inertia was introduced to the frequency control, which improved the behavior of the system under the violation of the power balance.…”

The article presents an original simulation model of a wind farm (WF) consisting of 30 wind turbine-generator units connected to the electrical power system (EPS) through power converters. The model is dedicated to the evaluation of the WF capabilities to participate in frequency and voltage regulation services in the power system. A system that allows for frequency and voltage control is proposed and implemented in the presented model. The system includes primary frequency regulation with synthetic inertia and secondary regulation available on request from the system operator. The concept of a reference power generation unit was introduced, according to which only one wind generator unit was modeled in detail, and the other units were replaced with simple current sources. Such a solution allowed for the reduction of size and complexity of the model as well as shortened the simulation time. Simulation tests were conducted in the PSCAD/EMTDC environment for an electrical power system composed of the wind farm, a synchronous generator, and a dummy load. The performance of the wind farm control system was analyzed in different operation conditions, and the control capabilities of the farm were assessed. Selected simulation results are presented and discussed in the paper. They illustrate the regulatory properties of the WF and confirm the correctness of the developed model.
