A General Equivalent Modeling Method for DFIG Wind Farms Based on Data-Driven Modeling

Abstract: To enhance the stable performance of wind farm (WF) equivalent models in uncertain operating scenarios, a model-data-driven equivalent modeling method for doubly-fed induction generator (DFIG)-based WFs is proposed. Firstly, the aggregation-based WF equivalent models and the equivalent methods for aggregated parameters are analyzed and compared. Two mechanism models are selected from the perspective of practicality and complementarity of simulation accuracy. Secondly, the simulation parameters are set through … Show more

“…Under the test conditions of Figure 7, the active and reactive power errors of the proposed equivalent node model are calculated according to Equations ( 2) and (3), respectively. To demonstrate the performance of the proposed model in detail, the differences in accuracy at different stages of the electromechanical transient period, i.e., the pre-fault phase, the early fault phase, the quasi-steady-state phase during the fault, the early fault-recovery phase, and the quasi-steady-state phase during the fault recovery [6,39], are illustrated in Figures 8 and 9. In addition, the average errors during the entire transient process are listed in Table 1.…”

“…Due to the length limitations and the specific research focus, an in-depth elaboration on the specific implementation steps of PSO will not be undertaken here. For a comprehensive understanding of the details and applications of PSO, we direct the reader to consult the reference provided in [33,34].…”
