A Brief Overview of Recent Advances in Distributed Accelerated Secondary Control for Islanded AC Microgrids

In the evolving landscape of modern power systems, islanded microgrids have contributed a significant role, offering superior resilience, power quality, and the efficient harnessing of distributed generators (DGs). The dynamic nature of such systems necessitates advanced control techniques to ensure stability and optimal operation. This article provides a brief review of recent advances in distributed accelerated (including finite-time, fixed-time, and prescribed-time) control strategies, with a particular focus on their use in the distributed secondary control of islanded ac microgrids. The spotlight is on the application of these distributed accelerated secondary control techniques in managing DGs. We investigate the fundamental principles of these techniques, their evolution over time, and pivotal technological advancements. A comparative analysis underscores the strengths and potential limitations of these control methodologies in context to DGs. Finally, we list some opportunities that these advanced control techniques offer in addressing challenges associated with the control of DGs in islanded microgrids, thereby paving the path for future research.
