Application of Active Disturbance Rejection Control in Different Parts of Renewable Energy Systems: A Survey

This survey presents an exhaustive view of the implementation of Active Disturbance Rejection Control (ADRC) across the renewable energy system components. ADRC stands out as a formidable control strategy, adept at navigating uncertainties and perturbations without the necessity for system modeling. This feature makes it particularly suitable for renewable energy systems, which are often subject to highly variable environmental conditions and inherent system nonlinearities. The survey covers the implementation of ADRC in wind energy systems, including turbine control for optimal power capture and grid integration for stable energy output. It also examines its application in solar photovoltaic systems with a particular emphasis on maximum power point extraction and inverter control to enhance efficiency and electricity quality. Furthermore, the use of ADRC in hydropower systems for regulating turbine and generator operations is discussed, highlighting its role in maintaining stable power output amidst fluctuating water flow. Additionally, the survey explores the integration of ADRC in hybrid systems, where it manages power distribution among different sources such as solar, battery storage, and wind to optimize overall performance. The advantages of ADRC, such as its adaptability, real-time disturbance rejection, and simplified implementation, are emphasized across these applications. In conclusion, the survey underscores the effectiveness of ADRC in enhancing the stability, reliability, and efficiency of renewable energy systems, positioning it as a crucial control strategy for advancing sustainable energy solutions.
