Methods of utilizing plasma actuating cascade arrays for actively controlling airflow over wind turbine blades are described herein. These methods may include providing plasma actuating cascade arrays that include dielectrics and electrodes. The electrodes and dielectrics are electrically operated to generate plasma clusters, and to induce directional airflows in response to the plasma clusters. The methods may also include configuring the plasma actuating cascade arrays based, at least in part, on characteristics of the wind turbine blades and characteristics of energy generation regimes and scenarios.
