Advancing Grid-Connected Renewable Generation Systems

If we look at the history of renewable energy sources (RESs), how it all began, and how rapidly they continue to develop, it can be argued that one of the main reasons is due to the rapid improvements in power electronics technology in interfacing the renewable source to the grid. Power electronics play an important role and are completely responsible for many important tasks, as well as having different power ranges where at a high penetration-level the RESs may cause instability if not carefully designed and implemented into the grid. In other words, power electronics have to efficiently harvest the maximum energy from the renewable energy sources/systems and then make it suitable, sustainable, and resilient, as well as transfer it to the power grid. Here it is important to apply suitable control techniques for such grid-connected systems, as it can be a challenge for the traditional grid to integrate the additional amount of electricity from an unpredictable and unsteady renewable energy resource. Contemporary grid-connected renewable generation systems stand in need of further advances in techniques for the utilization of renewable energy. This Special Issue focuses on challenging and advanced control methods to integrate RESs into power grid systems to enhance the performance of grid-connected renewable energy systems. This special issue on Advancing Grid-Connected Renewable Generation Systems contains the 14 papers we accepted; some of the most auspicious papers selected from those submitted. The selected papers have been organized into the followings groups, which are all very timely in renewable energy systems:
Part 1. → Control Techniques and AI (6 papers)
Part 2. → Power Converters (5 papers)
Part 3. → Rural Applications and Power Quality (3 papers)
