Emerging Active Power Filtering Techniques for Grid-Connected Photovoltaic Systems: A Review of the Latest Developments and Future Directions

This paper provides review of emerging active power filtering techniques applied to grid-connected photovoltaic systems. Grid-connected Photovoltaic systems have become gaining popularity due to their simplicity and reliability, and several publications have focused on different filtering techniques for PV systems. However, selecting the most appropriate technique can be challenging due to the varying merits and demerits of each technique. In recent years, to develop new techniques, many types of research are conducted based on the active power filter components of a photovoltaic system. This paper summarizes and compares filtering techniques, topologies, and control techniques to assist researchers and practitioners in selecting the most appropriate technique for their specific application. The paper serves as a reference for future research on grid connected PV systems with an active power filter. Overall, this review paper highlights the importance of selecting the most appropriate active power filtering technique for a specific application and provides a comprehensive comparison of available techniques. The paper aims to assist researchers and practitioners in making informed decisions about the selection and implementation of active power filtering techniques in grid-connected photovoltaic power systems.
