| As more wind energy is integrated to the power network, it becomes critical to study the influence of wind generation on existing power system. Real-time simulation and control of a grid-connected wind farm was investigated using a combination of off-line software and real-time hardware simulators. A reference doubly-fed induction generator (DFIG) based wind turbine generator system (WTGS) was model and validated using several off-line simulation tools. Then, the reference model was utilized for constructing the detailed wind energy systems. By performing various interaction studies using these systems, a set of benchmark results were obtained for the validation of the aggregated models. Finally, three models with different levels of aggregation were developed to improve the efficiency of the real-time electromagnetic transient study of the wind farm, and all of these models were implemented on the Real-Time eXperimental LABoratory (RTX-LAB) digital simulator. |
